Question

How are endocytosis and exocytosis different from diffusion?

Answer 1

Endocytosis and exocytosis include bringing something into the cell (endo) or eliminating it from the cell (exo), yet it doesn't get across the membrane by means of diffusion, it requires energy and is either taken in as a little membrane bound package, or eliminated.

Complete answer:
Diffusion is inactive, uncontrolled by the cell for nonpolar particles. While endo/exocytosis is selective and energy dependent.
The cell membrane of the cell is made out of nonpolar phospholipids that structure a bilayer. Therefore, it blocks polar particles from going through yet permits water and nonpolar molecules to pass. Diffusion is the development of particles down a concentration gradient. It happens latently with no control from the cell itself.
Endo/Exocytosis is the assimilation or secretion of polar molecules through the cell layer. It is an energy devouring cycle where the cell has unlimited control over it. In the event of exocytosis, the cell will coordinate a secretory vesicle that contains polar substances into the cell membrane. These vesicles are made out of similar phospholipids as the cell membrane. Making it conceivable to combine those vesicles with the layer and removing their substance into the extracellular space.
If there should arise an occurrence of endocytosis, the inverse happens. Part of the cell layer immerses the ordered substances and drag it inside as another vesicle

Note: Diffusion is the movement of molecules down a concentration gradient. It happens inactively with no control from the cell itself. Endo/Exocytosis is the ingestion or emission of polar particles through the cell membrane. It is an energy burning-through cycle where the cell has completed authority over it.
