Question

always occurs across a semi-permeable membrane.

• A. Osmosis
• B. Imbibition
• C. Diffusion

Answer 1

The correct option is A Osmosis

Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Diffusion also involves movement of solute molecules from a region of higher concentration to a region of lower concentration, but does not require a semi-permeable membrane.
Imbibition is the process by which dead or living plant cells adsorb water.
