Read each question carefully and provide your best answer based on your understanding of tonicity and osmosis.
1. What term describes a solution with a lower solute concentration than the cell's cytoplasm?
Isotonic
Hypertonic
Hypotonic
Plasmolytic
2. What happens to an animal cell when placed in a hypotonic solution?
It shrinks (crenates)
It swells and may burst (lyse)
It remains unchanged
It undergoes 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. When a plant cell is placed in a hypertonic solution, its plasma membrane pulls away from the cell wall, a process known as .
5. An isotonic solution causes no net movement of water into or out of a cell.
True
False
6. Turgor pressure is the pressure exerted by the cell wall on the protoplast in a plant cell, which helps maintain its rigidity.
True
False
7. Describe the process of osmosis and its role in maintaining cell homeostasis.
8. Compare and contrast how plant cells and animal cells react when placed in a hypertonic solution. Explain the structural differences that account for these reactions.
