Passive and Active Transport
Compare and contrast passive transport (diffusion, osmosis, facilitated diffusion) and active transport mechanisms.
Key Questions
- Differentiate between the various mechanisms of passive and active transport across cell membranes.
- Explain how cells maintain concentration gradients using active transport.
- Predict the movement of water and solutes across a semipermeable membrane in different tonicity conditions.
