[A] Crop Physiology

Crop Physiology: It is the study of plant functions and responses of crops grown in various environments. It is the underlying science that helps us to understand various aspects of plant growth and its body functions. This is very much like human physiology (Science of the mechanical, physical, and biochemical functions of normal humans or human tissues or organs.)
