simulation and will analyze and interpret their data in writing using technical
vocabulary (transport proteins, semipermeable, lipid bilayer, diffusion, osmosis,
homeostasis, passive transport, active transport) and science ideas (structure and
function).
Questions:
- List 3 things you've learned about cell membranes so far. (brain)
- Why do molecules like sugar, salt and water move into or out of cells? (brain)
- A semipermeable membrane has a 2 percent salt solution on one side and a 15 percent salt solution on the other side. What will most likely occur?
Answer choices for number 3:
A. Facilitated diffusion of salt until both concentrations are equal- B. Active transport of salt until all the salt is concentrated on one side
- C. Osmosis of water from a high concentration of salt to a low concentration
- D. Osmosis of water from a low concentration of salt to a high concentration
