1. Facilitated Diffusion 2. Osmosis 3. Active Transport 4. Passive transport 5. Diffusion 6. Active Transport 7. Active Transport 8. Exocytosis

Explanation:

Facilitated diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the process of diffusion of water molecules. Active Transport moves molecules from and low concentration to an area of high concentration by using ATP energy. Passive transport is the movement of molecules across the membrane without using energy. Diffusion is the movement of molecules down their concentration gradient. Active Transport moves molecules up the concentration gradient and across the membrane using energy from ATP. Exocytosis is active transport that requires energy, it is the fusion of secretory vesicles with the plasma membrane. Exocytosis exports molecules out of the cell.
