Question

Write true or false.

Osmosis includes diffusion, but not vice versa.

Answer 1

This statement is true.

Explanation:

Osmosis is a specific type of diffusion that refers exclusively to the movement of water molecules across a semipermeable membrane from a higher to a lower concentration. Regular diffusion applies to any substance (gases, solids, or liquids) spreading out anywhere, without needing a membrane. Therefore, all osmosis is diffusion, but not all diffusion is osmosis.
