Question

what is osmosis and diffusion?

Answer 1

osmosis:-  process of intermixing of water molecules from  higher water to lower water concentration is called osmosis through plasma memebrane.

diffusion:- process of inter mixing of gas molecules from higher to lower concentration is called diffusion . ( does not required plasma membrane ).

Answer 2

Answer:

Diffusion:-

It is process of movement of molecules from a region of higher concentration to a region of lower concentration is called diffusion.

• It involves movement of solute particles.

• It doesn’t involve semi-preamble membrane.

• It can occur to long distances.

Osmosis:-

Osmosis is movement of water molecules across a semi-preamble membrane from their higher concentration to lower concentration.

• It involves movement of water molecules.

• It involves semi-preamble membrane.

• It occurs to only short distances.
