Question

difine osmosis and diffusion ...? ​

Answer 1

Osmosis:

$\bullet$ It is the movement of water molecules from a solution of higher water potential to a solution of lower water potential.

$\bullet$ Through a semi-permeable membrane until an equilibrium is reached.

Diffusion:

$\bullet$ It is the spontaneous movement of molecules from a region of high concentration to a region of low concentration.

$\bullet$ The intermixing of the different particles of matter.

Answer 2

Hey Mate!!!

Here is your answer

osmosis

The movement of water molecules through selectively permeable membrane is known as osmosis. The movement of water across the plasma membrane is also affected by the amount of substances dissolved in water .Thus, osmosis is a passage of water from high concentration region to the region where it's concentration is low.

Diffusion

The spontaneous movement of a substance through selectively permeable membrane, from high concentration region to the region where it's concentration is low is known as diffusion.
