Starter:
1. How do passive and active transport
help a cell maintain homeostasis?
Practice: Pre-Lab Questions:
1. Diffusion is the net movement of
substances from an area of _____
concentration to an area of ______
concentration.
2. A cell’s membrane is semipermeable (also called “selectively
permeable”). What does this mean?
3. If a cell is in a hypertonic
solution, what is the direction of the
net flow of water and why?
