Branches of Biology - Introduction

Biology comes from the Greek word "bios" meaning life and "logos" meaning study.
Biology is the science that studies about various living organisms. A living organism
could be a one-celled bacteria or a several-celled organism such as an animal or a plant.
Biological science is classified into various branches, depending upon the organisms to
be studied, and is a vast field.

It is composed of many branches through which the scope of biology is broadened with
the unifying concepts that govern all study and research which is consolidated into a
single and coherent field.

Biology is the science that studies living organisms. However, as a science it has multiple
branches that intend to study issues such as evolution, nutrition, morphogenesis,
reproduction etc. There are a total of seven fields from which each branch hangs. Fields
such as animal, evolutionary, medical, environmental, microscopic structure, chemistry
related and other miscellaneous issues. There are many other Branches of Biology but
the above mentioned list is sufficient from the examination point of view.
