Passive Transport: Diffusion and Osmosis
Investigate the mechanisms of simple diffusion, facilitated diffusion, and osmosis across selectively permeable membranes.
Key Questions
- Explain how the concentration gradient drives the net movement of substances in passive transport.
- Compare the roles of channel proteins and carrier proteins in facilitated diffusion.
- Predict the osmotic effects on animal and plant cells when placed in hypotonic, isotonic, and hypertonic solutions.
