Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.

Biology is the science that studies life. Biologists are responsible for studying growth, function, origin, evolution and structure, as well as the distribution of living organisms.

Biology being a vast subject, it must be divided into several branches to facilitate study. Choosing a subject, however, can be a difficult task. If you want to look at all the options available to you and make an informed decision, you must select a biological subject from all of the biological discipline. Botany and zoology are the most important common areas and these are the first two branches formed in biology. 

Later, when the complexity of this subject was revealed, it was subdivided to facilitate learning. You now have areas such as evolutionary biology, cell biology, molecular biology and genetics.

These areas can not be studied independently because the bases and theories are the same for everyone. They are therefore part of the same general theme. their studies can not be completely separated. If you want to graduate with a major in biology, you must understand more than one subset. Each discipline has its role and meaning, but in general, the most important benefit of studying this vast subject is to better know the living organisms of the earth.
