Question

what is the difference between osmosis and diffusion? (any three points for class 9) ​

Answer 1

Osmosis-the movement of water from a region of their higher concentration to their lower concentration across the semi-permeable membrane is called osmosis
Diffusion-the movement of water or molecules from the region of higher concentration to the region of lower concentration until both concentrations are equal

Answer 2

Answer:

DIFFUSION

✔ Diffusion take place in any medium.

✔ It is the movement of a substances from the area of its higher concentration to the area of its lower concentrations.

✔ It does not require a semi-permeable membrane.

OSMOSIS

✔ Osmosis occurs only in liquid medium.

✔ It is the movement of water from the area of its higher water concentration to the area of Lower concentrations.

✔ It requires a semi-permeable membrane.
