1. FLASH CARD REVIEW: Cell Membrane Transport

2. What is the Cell Membrane composed of? Phospholipid Bilayer Proteins embedded

3. What is the Function of the Cell Membrane? Control movement in + out of cell Protection

4. Where is the Cell Membrane on Cells? The outer covering!

5. What is a Cell Wall in Plants composed of? Cellulose

6. What is the Function of the Cell Wall? Extra Structure Extra Protection

7. Where is the Cell Wall on Cells? The very outside! Outside & Around the Cell Membrane!

8. What types of organisms have Cells Walls? Plants Some Bacteria Fungi

9. What is Diffusion? The movement of particles (across a concentration gradient) from an area of HIGH to LOW concentration!

10. What is Osmosis? The movement of water particles (across a concentration gradient) from an area of HIGH water (low solute) concentration, to an area of LOW water (high solute) concentration.

11. During Diffusion & Osmosis, will particles ALL move to ONE side? No. Particles want to be evenly spread out. Want to reach equilibrium.

12. Some of your cells are immersed in a hypertonic solution. What will happen? They will shrink + shrivel. Water will rush out.

13. Some of your cells are immersed in a hypotonic solution. What will happen? They will swell + burst. Water will rush into the cells.

14. A saltwater organism is placed in a hypotonic solution. What will happen? Its cells will swell + burst. Water will rush into its cells.

15. What is a solute? The solid stuff you mix with liquid.

16. What is a solvent? The liquid stuff.

17. What does it mean to say that the Cell Membrane is Semi- Permeable? Only certain substances can diffuse in and out of the membrane.

18. What is the name for the type of membrane transport which requires ENERGY?! Active Transport

19. What are 2 types of Passive Transport? Diffusion Osmosis
