Read each question carefully and answer to the best of your ability. Refer to the provided diagrams where applicable.
1. Which of the following best describes the movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration?
Diffusion
Active Transport
Osmosis
Facilitated Diffusion
2. A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
It will shrink
It will burst
It will swell but not burst
It will remain unchanged
3. The primary component of the cell membrane that regulates passage of substances is the .
4. Active transport requires energy, typically in the form of , to move substances against their concentration gradient.
5. Describe the role of the cell membrane in maintaining cellular homeostasis, referencing the diagram above.
6. Facilitated diffusion requires energy expenditure by the cell.
True
False
7. A hypertonic solution has a lower solute concentration than the cell's cytoplasm.
True
False
Match each term with its correct definition.
8. Diffusion
a. Movement of water across a semipermeable membrane
9. Osmosis
b. Movement of solutes from high to low concentration
10. Active Transport
c. Movement against concentration gradient, requiring energy
11. Explain the differences between passive and active transport mechanisms in cells, providing an example for each. Discuss how these mechanisms are vital for a cell's survival.
