In every expect and process of life and every where science is too important. It is knowledge about all living things like animals, plants and humans include about their food and how can humans maintain their food and health.
                                                     It also knowledge about living organisms all organs like stomach, kidney, lungs, heart, brain and their diseases and how can we maintain our physically or mentally health.

There are three different branches of biology which study the different aspects of living things


The branch of biology which deal with the study of animals is called zoology. 


The branch of biology which deal with the study of plants is called botany.


The branch of biology which deal with the study of micro-organisms is called microbiology e.g viruses and bacteria etc.


The study of genes ans their roles in inheritance is called genetics. Inheritance means the transmission of characters from one generation to the other.

This branch deals with the study of the functions of different parts of living organisms.

Cell biology:

The study of the structures and functions of cells and cell organelles is called cell biology. This branch also deals with the study of cell division.


The microscopic study of tissues is called histology.


The study of internal structure is called anatomy.
