Question

define osmosis and diffusion​

Answer 1

Osmosis

The process of moving of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution to equalize concentration. The complete process does not require energy in order to take place.

For example, the absorption of water molecules from the soil through the roots of the plant.

Diffusion

The process of moving particles from a region of higher concentration to the region of lower concentration until equilibrium is reached.  Simple diffusion does not require energy in order to take place; however, facilitated diffusion requires ATP.

An example of diffusion of the perfume sprays into the air by spreading the aroma.

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. The overall effect is to equalize concentration throughout the medium.
