Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best describes the primary function of the cell membrane?
Protein synthesis
Regulating passage of substances
Storing genetic material
Producing ATP
2. A red blood cell placed in a hypotonic solution will likely:
Shrink
Swell and burst
Remain unchanged
Undergo plasmolysis
3. The movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration is called .
4. transport requires energy to move substances against their concentration gradient.
5. A plant cell in an isotonic solution will be , meaning it is neither turgid nor flaccid.
6. Describe the key differences between passive transport and active transport in terms of energy requirements and concentration gradients.
7. Explain how the cell membrane maintains homeostasis within a cell.
8. Diffusion is the movement of particles from an area of lower concentration to an area of higher concentration.
True
False
9. Facilitated diffusion requires ATP to move molecules across the cell membrane.
True
False
10. Observe the diagram of the cell membrane below. Label the following components:
A. Phospholipid bilayer B. Integral protein C. Peripheral protein D. Glycoprotein E. Cholesterol
