Define osmosis. Give its types.
Answer
Osmosis : It is the process of diffusion of solvent or water molecules from the place of its higher concentration to the place of its lower concentration across a semi permeable membrane.

Osmosis is of two types :

(a) Exosmosis (b) Endosmosis.

(a) Exosmosis : It is the process by which solvent molecules diffuse from inside to outside across a  semipermeable membrane.

(b) Endosmosis : It is the process by which solvent molecules diffuse from outside to inside of a cell across a semi-permeable membrane.
