Diffusion
It is the net movement of particles from an area of high concentration to an area of lower concentration. It is a passive process- does not require energy
1 of 6
Osmosis
It is the movement of water molecules across a partially permeable membrane down a water potential gradient from an area of higher water potential to an area of lower water potential. It is a passive process- does not require energy
2 of 6
Facilitated Diffusion
It is the net movement of particles from an area of higher concentration to an area of lower concentration. It uses carrier proteins for larger molecules and channel proteins for smaller ions and polar molecules. It is a passive process
3 of 6
Active Transport
It is the movement of molecules against a concentration gradient. It uses carrier proteins and is an active process- requires energy (ATP)
4 of 6
Endocytosis
It is the movement of larger molecules into a cell. Plasma membrane surrounds a substance then pinches off to form a vesicle. It is an active process- requires energy (ATP)
5 of 6
Exocytosis
It is the movement of molecules out a cell. The vesicle fuses with the plasma membrane and releases its contents. It is an active process- requires energy (ATP)
