Question

Give the differences between diffusion and osmosis.

Answer 1

OSMOSIS	DIFFUSION
Only the solvent (Fluid) part moves.	All the particles (gas,liquid and solid) can move.
The movement is only in one direction.i.e, from a less concentrated solution to a more concentrated solution.	The movements occurs in all directions or from higher concentration to lower concentration.
It requires a semi-permeable membrane because it is porous.	It don't require a semi-permeable membrane.
It is of two types: endosmosis (movement of water inside) and  exosmosis (movement of water outside).	It includes dialysis (diffusion of protein particles etc)
For example: swelling up raisins when placed in fresh water, roots of plants taking up water from the soil.	For example: Diffusion of perfume particles in the whole room, color dye diffusion in water.
