Answer:
Passive Transport
Diffusion - the movement of substances from an area of higher concentration to one of lower concentration.
Osmosis - the movement (or diffusion) of solvent through a semipermeable membrane.
Facilitated diffusion - is the process of transporting molecules or ions across a biological membrane from an area of higer concentration to a lower one with the help of a transport protein.
Active Transport
Protein pumps - active transports that pump ions and molecules against their concentration gradient.
Exocytosis - the process of vesicles fusing with the plasma membrane and secreting these material packages to the otside of the cell.
Endocytosis - the process of capturing a substance or particle from outside of the cell by engulfing it with its membrane, and bringing it into the cell.
