Osmotic pressure is created by the presence in a fluid of small diffusible molecules that easily move through the capillary membrane. true false

The statement is False

Explanation:

Osmotic pressure is created by the movement of water across the semi-permeable membrane. In osmosis water moves from an area which is having low solute concentration to the area which is having high solute concentration.  

So in osmosis, the movement of water takes place not molecules. This pressure is caused by differences in solute concentration across the plasma membrane and water moves to high concentration to equalize the pressure. Therefore the statement is wrong.

a, i am pretty sure.
