Differentiate between osmosis and. diffusion????
Answers
Answer:
1. Definition:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane.
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Diffusion Osmosis
1Any type of substance moves from area of highest energy or concentration to region of lowest energy or concentration. Only water or another solvent moves from a region of high energy or concentration to a region of lower energy or concentration.
1Diffusion can occur in any medium, whether it is liquid, solid, or gas. Osmosis occurs only in a liquid medium.
2Diffusion does not require a semipermeable membrane. Osmosis requires a semipermeable membrane.
2The concentration of the diffusion substance equalizes to fill the available space. The concentration of the solvent does not become equal on both sides of the membrane.
3Hydrostatic pressure and turgor pressure do not normally apply to 3diffusion. Hydrostatic pressure and turgor pressure oppose osmosis.
4Diffusion does not depend on solute potential, pressure potential, or water potential. Osmosis depends on solute potential.
4Diffusion mainly depends on the presence of other particles. Osmosis mainly depends on the number of solute particles dissolved in the solvent.
5Diffusion is a passive process. Osmosis is a passive process.
5The movement in diffusion is to equalize concentration (energy) throughout the system. The movement in osmosis seeks to equalize solvent concentration (although it does not achieve this).
