There is a special method for learning biology yourself at home from scratch. To complete it, you just need not to worry, be patient, have good textbooks and visual aids. Self-organization and a large amount of time for preparation play a significant role in success.
If you need to take an exam in biology, but don’t have money for a tutor, then you can study this natural science yourself. First, you should assess your level of knowledge. If this is zero, then you need to set aside enough time for independent study of biology in order to thoroughly study all the topics and understand them. To do this, you should familiarize yourself with the Unified State Exam program and draw up a detailed work plan. You need to calculate how many topics the program includes and how long it will take to process each one.
It is necessary to prepare for each topic separately, and not for all at once. The branches of biology are logically interconnected. The acquired knowledge is increased step by step. Therefore, basic terms and concepts are studied first, and then more serious topics. Only when one topic is learned well can you move on to the next. The main condition for independent learning is strict adherence to the schedule. By shirking and leaving everything until the very last day, you may never learn anything. If biology is relatively easy, then you can spend at least one week studying it. If natural science is very difficult to understand, this period must be increased.
You should acquire textbooks for all biology courses, get explanatory manuals, and retrieve biology notebooks from all your years of study from your own archives. You need to read in short paragraphs. After each reading, you need to understand the material well and write a short summary on it from memory. This way you can highlight the main and important points for yourself. When studying a subject, the school textbook should be considered the fundamental source of knowledge. Other sources of information are best used as clear explanations or as useful additions to the textbook, but not as primary material.
When writing a summary, it is recommended to make various drawings, diagrams, graphs and tables by hand that briefly convey the essence of what is being read. Such notes are well remembered and associated with the desired section. The notebook fields should be left blank, leaving space for future notes and clarifications. You need to memorize your manuscript and check your knowledge using the table of terms. If there are unfamiliar names in the table, they must be included in the notes in the section to which they relate.
For each topic, you should complete half of the tasks and check your level of self-preparation. If the assignments fail, then the difficult topic needs to be learned better. If the tasks are given easily and correctly, then you can solve the second part of the tasks, thereby developing skills. After completing all the tasks, you need to work on your mistakes: highlight all the tricky questions and read them again.
Required course program
To know which topics in biology you need to learn for the exam, you need to familiarize yourself with the full course program. School biology education includes the following sections:
- Biology is the science of living nature. You need to know the definition of the term “biology” and methods of its research. Learn the signs of living things, cell structure and metabolic processes.
- Cell as a biological system. This includes the following subtopics: cell diversity, cell structure, functions of its organelles, metabolism, nutrition and cell reproduction.
- Organism as a biological system. To master this section, you need to understand what it is: single- and multicellular organisms, viruses, auto- and heterotrophs, the principle of the formation of tissues from cells, the reproduction of organisms and genetics.
- Diversity of organisms. It is necessary to master taxonomic categories, learn the 5 kingdoms of living organisms, and remember the structural features and vital functions of chordate organisms.
- Man and his health. This section includes the structure and functioning of human tissues, organs and systems, knowledge of personal hygiene.
- Superorganismal systems and the evolution of the organic world. You should familiarize yourself with the theories of evolutionary ideas, the diversity of existing species, and the history of human origins.
- Ecosystems and their inherent patterns. We must remember what an ecosystem is, what its varieties are, how the cycle of substances occurs in nature. It is also necessary to familiarize yourself with the teachings of Vernadsky and learn what the bio- and noosphere are.
To make it easier to study the material, topics need to be arranged in a logical order. First, the basics of all living things, such as cells, are studied. Then more general items, such as fabrics. Next, the already studied tissues are formed into organs or the process of evolution from protozoa to multicellular is studied. You just need to understand that biology is not a collection of different sections, but interrelated topics that flow from each other.
What is the easiest way to understand a subject on your own?
Without a tutor, of course, it is more difficult to understand biology on your own. But there is nothing scary in this science. It just needs to be perceived easily, as something educational and interesting, then its memorization will be easier - through awareness of each topic.
It is always recommended to prepare for the exam using special textbooks. They contain all the necessary information. But they are also oversaturated with complex terms that make it difficult to perceive and understand what is written. Therefore, in addition to textbooks, it is advisable to use various manuals written in simple layman’s language. They will help you interpret and understand what is presented in the textbook. It is better to read silently, because when speaking words out loud, attention is scattered and the information is remembered worse.
Scientific films can be used as additional auxiliary educational material. They will cover topics that are difficult to understand in detail and clearly. In addition, when watching educational films, visual and auditory memory works, which gives a higher level of memorability.
You can’t leave a topic you’ve read unlearned. If after multiple readings the topic remains unexplored, it needs to be analyzed in more detail. You cannot move on to studying the next material if you have not learned the previous one. You need to study in small portions. After reading the page, you need to briefly tell yourself what was discussed. If everything is clear, you should continue reading. If not, read it again. Constant self-monitoring of knowledge will allow you to identify gaps in memory and evenly learn all the material.
Why does a person need knowledge of biology?
This is general knowledge, like chemistry, higher mathematics, astronomy and philosophy. Will you need astronomy in your life? Unlikely, seriously. But at school they study it to give an idea of the existing sciences. Expanding your horizons, improving your worldview, if you like. Biology is needed in order to have an idea of the living world around us, to know at least superficially what living organisms are, how they live and develop. This is not bad, and the science is not complicated, study it and remember it, it’s even interesting.
Biology gives a person an idea of living beings, their structure, diversity and relationships in nature. School education is designed in such a way that people can have an idea of what they may encounter in life. We encounter wildlife every day when we go outside, so we simply must have at least a general idea of wildlife. Again, so that there are no questions like what will happen if you cross a gorilla and a parrot, or attempts to grow tangerines in Yakutia. Many practical fields of knowledge, such as medicine, agriculture, sports, psychology, organic chemistry, etc. use knowledge of biology. Biology is not a theoretical science, it is an experimental science, so its knowledge will not change much from politics and ideologies, which is why it is also valuable. This science is part of a group of natural science disciplines that are the basis of world knowledge about the world. Therefore it is worth studying.
Modern man needs biological knowledge to understand his place in nature. You need to know and understand that in nature everything is interconnected and by disturbing the ecological balance we make it worse for ourselves and our children. Knowledge of biology helps in many areas of science and real life.
Without knowledge of biology, life would probably end. A very important subject indeed. But he is not particularly popular or loved by schoolchildren. But in vain. What does biology study? You and me, animals, nature. It is important for us to know the functioning of our body, what and how happens in it. Thanks to this knowledge, for example, doctors treat us. Biology is their main subject. And if everyone studied biology well, they could know their body better and get sick less.
Biology helps us understand the world, grow crops and much more.
So biology is literally the science of life.
Knowledge of biology is necessary for a person of any age in order, first of all, to understand the processes that occur in his body. This broadens one's horizons and allows a person to make correct judgments about his physiology.
Equally important is understanding what happens in nature with other living organisms.
But for schoolchildren, knowledge of biology is necessary in order to enter higher educational institutions, where the major subject is biology. These are medical, pedagogical, sports, and psychological universities. And also those departments and faculties that train specialists for agriculture, veterinary medicine, nutrition institutes, and astronautics.
Students studying biology need this knowledge for scientific activities, to work on a dissertation on biological topics...
This is a good science - biology. I remember at school I always looked at microscopes with interest!))
Advances in medicine directly depend on knowledge of biology.
About life. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms in an ecosystem. Through its research, this science is intended to convince people of the need for a caring attitude towards nature, knowledge and observance of its laws. Many call it the science of the future, and they are absolutely right.
Such different biology
Biochemistry deals with the study of the substances that make up all living things. Botany is the study of plants, including crops. Cellular biology is responsible for the study of the cells that make up Ecology observes how organisms interact with their environment. Evolutionary biology is the study of the origins and temporal changes in the diversity of life forms.
Genetics studies heredity, molecular biology - molecules, physiology - the functions of organisms and their parts, zoology - animals, including their behavior. And what’s most interesting is that all these sciences are inextricably linked with each other; it is impossible to study zoology without understanding evolution, physiology and ecology. You also cannot study cell biology without knowing biochemistry and molecular biology and so on.
History of biology
Since ancient times, humanity has known the importance of biology in human life. Even ancient people were forced to study animals and plants in order to hunt and provide themselves with food and treatment. In ancient times, Aristotle was the author of several works on scientific zoology. It is known that he carried out extensive research on marine organisms and plants. His student, Theophrastus, wrote one of the earliest known texts on botany, dating back to 300 BC, namely on the structure, life cycle and use of plants.
The Roman physician Galen used his experience treating gladiators after battles in the arena to write works on surgical interventions. During the Renaissance, Leonardo da Vinci, at the risk of public censure, created detailed anatomical drawings that are still considered among the most beautiful ever created. One of the first illustrated books on biology was written by the German botanist Leonardo Fuchs in 1542.
Passion for biology
Biology is the science of life, the study of which, after the invention of microscopes, opened new worlds and horizons for scientists. In 1665, using a simple microscope, he found out that plant tissue consists of rectangular blocks, which he called cells. In 1676, Anton von Leeuwenhoek published the first drawings of living single-celled organisms.
The biology craze began in the Victorian era. Throughout the 19th century, the natural sciences were something of a mania. Thousands of new species of animals and plants were discovered, and new brave daredevils appeared in the person of botanists and entomologists, who were not afraid to put forward new hypotheses and assumptions. Charles Darwin published his legendary theory that changed the world forever.
Biological revolution
The 20th and 21st centuries marked the beginning of a real biological revolution. In 1953, the structure was deciphered and studied. Gradually, all areas of biology are expanding and affecting all aspects of life. Why is it necessary to study biology? This science is inextricably linked with medicine. Together, this fundamental knowledge can work real miracles.
Answering the question of why you need to study biology, it is worth noting the importance and limitless possibilities that it provides. The economies of states depend on proper management, including environmental resources. Humanity can pave the way for preserving forests, seas and oceans, using them to produce enough food. You can learn to “grow” batteries from bacteria or build lightweight buildings from bioluminescent mushrooms.
Biology as a science
Biology is the science of life that covers all aspects of the study of living organisms, from the concept of genes to the management of entire ecosystems. Why is it necessary to study biology? By researching, you can learn everything about animals, plants and microorganisms at the genetic level, their cellular structure and interaction in natural conditions.
Translated from Greek, biology is the science of life and living organisms. An organism is a living being consisting of one (bacteria) or several cells (animals, plants, fungi). Biology often overlaps with other sciences. Biochemistry, toxicology and biology, chemistry and medicine, biophysics - with biology and physics, stratigraphy - with biology and geography, astrobiology - with biology and astronomy are interrelated.
Why is it necessary to study biology?
Biology is an integral part of the life of society, since from time immemorial humanity has been directly dependent on the natural world. It is a core discipline vital to human existence. Studying natural sciences helps develop advanced technologies that can be used to explore problematic issues that seem impossible to solve.
Why should you study biology? Every year, many higher and secondary educational institutions open their gates and invite the most ambitious and inquisitive applicants who want to connect their lives with this multifaceted science. Admission and study offer prospective students a wealth of opportunities for their education, research and careers.
Fascinating Science
Already at school, children are told why they need to know biology. This is an amazing science that involves a detailed study of plant and animal life, both theoretically and practically. It is an excellent subject of study for self-education, and importantly, it can be very useful for careers in the fields of medicine, ecology, health care and the food industry.
Why study biology? The results of numerous biological studies can help solve many pressing problems of our time. This concerns the protection of health, provision of food resources, as well as the preservation of diverse forms of life on Earth. The destruction of natural treasures can ultimately have a negative impact on human existence, which is why it is so important to care for and protect the world around us, as well as study and research the vital science of biology.
What is biology? In the school curriculum there is a subject with this name, in addition, the word “biology”, “biological” is often found in the media and the Internet.
We will talk about what the science of biology studies in this article.
Where did the word "biology" come from?
Biology is the science that studies living things. The word is derived from the Greek words “bios”, i.e. life, and "logos", which means teaching. Accordingly, biology is the study of life.
Like the word, the science of biology originates in ancient times. People have long been interested in the features and patterns of existence of surrounding living beings: animals, birds, insects, plants, etc.
In ancient times, this information was vital because many people supported their existence through hunting, farming and animal husbandry.
Agriculture was then carried out using primitive methods, and the yield of cultivated plants was very low, since breeding work was in its infancy.
Things were not the best in animal husbandry either - there were no modern breeds of animals distinguished by high rates of meat, milk, wool and other products, but epidemics were frequent, reducing the number of animals.
Those who chose hunting as their craft were in a more or less advantageous position: there was more game than today, and it could often be found not far from human settlements.
However, hunting weapons were also quite primitive: homemade bows and arrows, spears, snares, traps. The hunters were helped by their knowledge of the habits of the game and their own dexterity.
Under these conditions, the study of animals and plants, their methods of existence and reproduction was a condition of survival for most people. Of course, for many centuries the only way of research was observation and experiments on crossing closely related animals and plants. 
However, already by the eighteenth century, biology had a fairly extensive store of knowledge, which is often used by modern researchers.
What does biology study?
The most general definition is that biology studies. The interests of this science include the origin of living beings, their development, way of life, interaction with each other and with the outside world.
Biological scientists are interested in life in all its manifestations, from the molecular level to the most complex biosystems.
One of the leading directions is the study of the origin of life: under what conditions and why did life originate on our planet? Is it possible to repeat this experiment?
Closely related to it is genetic engineering - the ability to artificially create new species of living beings that would have predetermined properties. So far, humanity has only taken its first steps in this area of biology, but the prospects here are truly stunning.
The study of bioecosystems is another relevant area of biology, which helps to understand the relationship between the life activities of a wide variety of creatures.
This is very important for planning future human actions on the planet, because we must not only transform nature for our convenience, but also preserve it as clean and holistic as possible. 
We must not allow the death of entire populations of living beings, as this impoverishes the gene pool of the Earth.
An extremely important area is human biology. This includes the creation of new drugs and methods for treating diseases, and the improvement of heredity, and the discovery of new human capabilities to increase his vitality and efficiency. Man is one of the most interesting objects for biologists to study.
What is biology for?
The famous Danish scientist Niels Bohr once said: if the twentieth century was the century of physics, then the twenty-first will be the century of biology. Today we can already be convinced that the great thinker was right.
With the help of biology, we can solve many different problems facing humanity:
- create new super-yielding plant crops and super-productive animal breeds in order to forever rid humanity of hunger;
- develop new methods for treating diseases that would heal the entire body, and not just one diseased organ;
- extend human life;
- delay the aging of the body;
— solve the problem of environmental pollution.
There is no doubt that this is only part of the challenges facing biology in the twenty-first century. 
Just as at the beginning of the twentieth century it was impossible to imagine what problems antibiotics would create for modern medicine, so we cannot imagine what problems biology will solve at the end of this century.
The only thing that can be said is that new great discoveries and amazing knowledge await humanity.
Everything related to life on Earth is part of biology, which is the study of life. Why is biology needed? This science affects many aspects of human existence; there are a huge number of professions that in one way or another affect this fundamental science. This list includes career advancement and limitless employment options.
Biological Sciences
Why is biology needed? Biological sciences are one of the broadest and most important fields in the world today. Biology covers everything from the molecular study of life processes to the study of animal and plant communities. What can you do with a biology degree? Depending on individual interests and preferences, you can choose any profession to your liking in areas such as healthcare, medicine, the environment, education, biotechnology, criminology, politics and many others.
Why should you study biology?
What is biology for? Studying it teaches you to ask questions, make observations, evaluate evidence, and solve problems. Biologists learn how living things interact with each other, what they are made of, and how they develop. They study evolution, natural history and the protection of rare species of plants and animals, and also engage in research into the interactions of living organisms with light, the environment and each other.
What do biologists do?
Biologists study the natural world using the latest scientific technologies, tools, and methods, both in the laboratory and in the natural environment, to understand how living systems work. Why do they need biology? Many work in exotic locations around the world, and what they discover may have practical applications to solve specific problems. Biologists are developing public health campaigns to combat diseases such as tuberculosis, AIDS, cancer and heart disease. Their mission is also to prevent the spread of rare, incurable diseases, such as the notorious Ebola virus.
What professions require biology?
Where is biology needed? Knowing biology can lead to a career in pharmaceuticals, biotechnology, or medical research. These sectors help to better understand the natural world, address issues of personal well-being, and also address the topics of environmental degradation that threatens human health and the depletion of natural and food supplies.
Veterinarians who treat sick and injured animals, doctors, dentists, nurses and other healthcare professionals support the overall health and well-being of their patients. Many of these professions require additional education and training. In the field of environmental management and environmental protection, biologists are engaged in solving environmental problems and preserving natural diversity for future generations.
