Concepts and Objectives:





Relate diffusion and equilibrium.
Describe how passive transport occurs.
Relate osmosis to solute concentration.
Explain how active transport differs from passive transport.
Describe how large molecules move across a membrane.
Distinguish between hypertonic, hypotonic, and isotonic solutions, and give
an example of how each affects an animal cell.
Make a concept map of the different types of transport, which require energy, how
molecules move, and which require transport proteins.
Review of Transport Worksheet:

Review what happened when salt was added to the plant cells.
15% salt was what type of solution compared to the normal plant cell
environment?
What happened to the central vacuole, and chloroplasts?
What effect did the cell wall have on the plant cell?
