The cellular process diffusion does not require cellular

Diffusion is a process that occurs when a substance such as water, molecules, and ions, which are usually needed for various cellular processes, enter and leave cells. The way that cell diffusion happens is by molecules moving from an area of high concentration to an area of low concentration. This usually occurs until both molecules have the same amount of the substance and it is distributed evenly.

Both of them have a nucleus, golgi apparatus, cell membrane, smooth and rough endoplasmic reticulum, lysosome, and ribosomes.
