Question

The movement of water through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration is called?

1) diffusion
2) osmosis
3) denaturation
4) metabolism
5) solubility

Answer 1

2) Osmosis is the movement of water through a semipermeable membrane from lower solute concentration to higher solute concentration. Hence, option 2) is correct.

Step-by-step explanation:

Osmosis is the movement of water through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. It is a special case of diffusion and depends on the concentration gradient.

When two solutions of different concentrations are separated by a semipermeable membrane, water and solute particles move across the membrane to balance the concentrations.
