1
Q
Diffusion
A
Net movement of particles from a high concentration to a low contentration
2
Q
Osmosis
A
The movement of water from a high water potential to a low water potential
3
Q
Active transport
A
Substances move into the cell against the concentration gradient. Moves from low concentration to high concentration. This process needs energy.
4
Q
Factors that affect rate of movement of substances
A
Surface area to volume ratio, distance, temperature, concentration gradient, thickness of membrane/wall
