CBSE VII Biology

Biological Sciences is the study of life and living organisms. It is also called as “Biology”. The Greek word ‘bio’ means life and ‘logos’ means study of. In the late 1700s Pierre-Antoine de Monet and Jean-Baptiste de Lamarck coined the term biology.

Earlier study of living things was restricted to the pure Science like Botany and Zoology that together comprise the Biology. But as the time passed new branches evolved, new technologies developed in pure subjects as well as in applied fields, which gave rise to a very broad science called Biological Sciences.

Biological Sciences is an extensive study covering the minute workings of chemical substances inside living cells, to the broad scale concepts of ecosystems and global environmental changes. It is also concerned with the physical characteristics and behaviors of organisms living today and long ago, how they came into existence, and what relation they possess with each other and their environments. Intimate study of details of the human brain, the composition of our genes, and even the functioning of our reproductive system are dealt in Biological science. Today it is also called by new name- Life sciences.
