Biology is a study about living plants and animals in this world. This subject has much importance to man and hence it is taught in every educational school. Biology is broadly divided into two subjects as botany and zoology.Botany is one which deals about plants and zoology deals with study of animals. Every minute aspect of plants and animal life is covered in the subject starting from birth or germination, growth, reproduction and their death. Further it has many diverse branches like microbiology, biochemistry, biotechnology, genetics etc for those interested in deeper knowledge of biology.
Study of importance of plants in botany makes us understand their role in human survival. They are the resources which provide many of the basic needs like food (for both humans and animals in the form of carbohydrates, proteins and fats), clothing (they are the largest supply of fiber as cotton required to make cloth), shelter (as they provide interior and exterior furniture), medicines (as they are greatest source of medicine). These medicines have advantages of better body assimilation, compatibility and low unto side effects. Hence study of botany helps us to further discover their uses to human survival
Study of animals is vital because it gives us knowledge about the types of animals available, their living habits, food chains etc. It helps for better study on animals useful to humans like those which provide food (eggs, milk,honey & meat), which contribute for clothing (wool from sheep), which are dangerous when encountered for man etc. Some of the animals are useful in making of drugs and medicines useful to man. For example many of the anti-bodies are prepared by using animals as reservoirs. We can also understand the role of animals in maintenance and balance of our environment.
Biology is further divided into branches like biochemistry, microbiology, biotechnology for further and better understanding of biology in human use.
