cellular physiology

Saturday 27 January 2018

Definition : Cell physiology is the biological study of the activities and the functions that take place in a cell to keep it alive.

The term "physiology" refers to all the normal functions that take place in a living organism.

All of these activities in the cell could be counted as following ; nutrition , environmental response , cell growth , cell division , reproduction and differentiation.

The differences among the animal cells , plant cells and unicellualr microorganisms shows the essential functional similarity eventhough those cells have different structures.

Absorption of water by roots , production of food in the leaves , and growth of shoots towards light are examples of plant physiology.

The heterotrophic metabolism of food derived from plants and animals and the use of movement to obtain nutrients (even if the organism itself remains in a relatively stationary position) are characteristic of animal physiology.
