Diffusion:-
Definition: Diffusion is the transport of molecules from a region of high concentration to a region of lower concentration.

Osmosis:-
Definition: Osmosis is the movement of water from an area of high water potential to an area of low water potential, through a partially permeable membrane.

Endocytosis and Exocytosis:-
Definition: Endocytosis is the movement into the cell via the cell membrane of any substance.
Exocytosis on the other hand is the movement of anything out of the cell via the cell membrane.

Active Transport:-
Definition: Active transport works against the concentration gradient and requires energy when moving ions or molecules over the membrane. This means that substances can move over the cell membrane even if there is a higher concentration already within the cell but it does require ATP.
