1
Q
Osmosis
A
movement of water through a differentially permeable membrane from lower solute concentration solution to high
2
Q
Endocytosis
A
taking materials in via a vesicle (phagocytosis - solid) (pinocytosis - liquid)
2
Q
Exocytosis
A
Materials leaving cell via vesicle
2
Q
Simple diffusion
A
movement of materials from a high concentration to low until equilibrium is acheive
3
Q
Facilitated transport
A
passive (no energy required) process by which molecules are transported across the plasma membrane with the help of membrane proteins.
4
