Answer 1

1. Diffusion: Diffusion is the movement of the substances from higher to lower concentrations.

2. Osmosis: The movement of solvent molecules from a region of higher concentration to a region of its lower concentration across a semipermeable membrane is termed osmosis.


3.Active transport: Active transport is the movement of molecules from a region of lower concentration to that of higher concentration against the concentration gradient.
