Question

How would you explain the process of diffusion and osmosis?

Answer 1

Diffusion and Osmosis are both types of PASSIVE TRANSPORT - that is, no energy is required for the molecules to move into or out of the cell. Sometimes, large molecules cannot cross the plasma membrane, and are "helped" across by carrier proteins - this process is called facilitated diffusion.

Answer 2

diffusion is the process of travelling of matter from high concentration to low concentration, whereas osmosis is the same travelling of matter especially water from high to low concentration through a semi permeable membrane
