Biology Unit 4 Day 3

Learning Objective: Students will learn about cell membranes by watching videos and will describe them in writing using technical vocabulary (transport proteins, semipermeable, lipid bilayer, diffusion, osmosis, homeostasis, passive transport, active transport) and science ideas (structure and function).


Questions:

1. What is homeostasis? (book)
2. List 3 functions of the cell membrane (book)
3. What would happen to a cell if the fatty acids in the cell membrane became soluble in water?

Answer Choices for Number 3:

A. It would increase the rate of cell division. B. It would stop all substances from passing through. C. It would decrease the ions needed by a mitochondrion. D. It would cause the cell to lose all its contents to the outside.
