Explanation:
Answer:
Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.
Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.
Explanation:
Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.
