Question

define osmosis and diffusion​

Answer 1

Answer:

Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. ... Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.

Answer 2

Answer:

• Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.
• Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
