The word
Biology comes from the Greek word Bios and Logos. Bios means life and logos means knowledge. So from that we
can say that Biology is a sector of science which is concerned with the study
of living organisms. It discusses about the structure, function, growth,
evolution, distribution and taxonomy of living organisms. In modern age biology
has covered a vast and divers field which is composed of many branches
and sub branches. Biology recognizes the cell as the basic unit of life, genes
as the basic unit of heredity, and evolution as the engine that propels the
synthesis and creation of new species.
