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 belong.
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.
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.

Answer from Alexander Tyufyakov[newbie]
Why does a person need knowledge of biology?
While studying at school, much of the knowledge acquired there seems inapplicable in real life. However, this cannot be attributed to biology. Why does every person need to study this science?
Biology is a science that studies the basics of life and interaction of living organisms. The entire biosphere surrounding man belongs to the sphere of interests of this branch of knowledge. Therefore, biology is important, firstly, as a source of knowledge about the world around us. With the help of this science, a person will be able to learn more about the living nature around him. But, in addition to a purely cognitive function, this section of biology also has practical significance. It is knowledge of biological laws that gives an understanding that in nature everything is interconnected, and it is necessary to maintain a balance between different types of creatures. You can't just wipe out one species without damaging the entire system. Such knowledge can convince a person that the ecological balance must be protected. Another branch of biology is, in fact, the study of man himself. This knowledge is also important for everyone. Biology has become the theoretical basis for medicine, giving it the opportunity to understand the specifics of the human body. But every person needs to know their own characteristics as a biological species. This will help you better understand how to organize your life in terms of nutrition, physical and mental activity. Rational use of one's own body can significantly increase labor productivity. Biology is also useful in the field of economics, especially in agriculture. Knowledge of the laws of development of living organisms helped people learn to breed new species that are more suitable for cultivation in an artificial environment. This significantly increased yields and meat production, which is especially necessary for humanity during a period of population growth and declining natural reserves.
From the above we can conclude that the study of biology has changed many areas of human activity. But basic knowledge in this science is also necessary for non-specialists in order to successfully navigate the modern world and make the right choice, for example, in situations related to environmental pollution or their own health.
B Biology - what kind of science is this? Why is it needed, and the most important question is who? What sections is it divided into? For which specialties is biology needed like air? We will consider all these questions below.
What is biology?
Biology translated from Greek means the science of life. This subject is considered a humanities science, which many do not give due importance. In the age of new technologies, preference is given to physics and mathematics, but biosciences are not far behind them. Biology is a science that studies all kinds of living organisms and their interaction with the environment. The first documented word “biology” appeared relatively recently: about 200 years ago, a guy named wrote a 6-volume book called “Biology, or the philosophy of living nature.”
This science also studies such aspects as growth, development, structure and, starting from the simplest microbe and ending with the study of alien life forms.
What sections is it divided into?
As mentioned above, this science is simply immense and it is not possible to fully cover all its sections and subcategories, so we will give the largest ones as an example. The science of life in its structure, roughly speaking, is divided into the following sections:
- Botany- section studying , and similar organisms;
- Zoology- section studying and protists;
- Microbiology- section studying microorganisms and;
- Biochemistry— a section studying the chemical foundations of life;
- Biophysics— a section studying the physical foundations of life;
- Molecular biology— section studying the interactions of molecules of living organisms;
- Cytology— section studying the composition of cellular organisms;
- Anatomy— section studying the structure of tissues and human development;
- Physiology— section studying the physical and chemical functions of organs and tissues;
- Ethology- section studying the behavior of living beings;
- Ecology— a section studying the interdependence of various organisms and their habitats;
- Genetics- section studying the patterns of heredity and variability;
- Biodevelopment— a section studying the development of an organism in ontogenesis;
- Evolutionary- a section studying the origin and historical development of living nature.
This is not the entire list of sections into which it is divided; we will consider the remaining sections in the future.
Where is it needed?
To the question where is biology needed? you can safely answer everywhere, because any moment of human life, if not directly, then tangentially, still affects its sections. If you take medicine, then it’s probably a little scary to go to a doctor who doesn’t even know human anatomy. If you take sport, then it is useless to go to a trainer who does not know the physiology of the human body. If you take archeology, then an archaeologist who does not understand the behavior of an organism (ethology) will probably be able to find little. In general, there is no such thing where even the slightest knowledge on this subject would not be useful.
For what specialties is it needed?
There are quite a lot of specialties that need the subject of development and life like air and there is no point in listing them all. The most popular biological specialties:
- Medic
- Formatsevt
- Biology teacher
- Vet
- Psychologist
- Agronomist
- Food Processing Technician
- Scientist
- Athlete
- Nutritionist
In fact, there are quite a few specialties, but biology is a fundamental subject for entering a university.
