Read each question carefully and answer to the best of your ability. Diagrams are provided where necessary to aid your understanding.
1. What is the net movement of water across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration?
Active transport
Diffusion
Osmosis
Facilitated diffusion
2. A plant cell is placed in a hypotonic solution. What will most likely happen to the plant cell?
It will shrink (plasmolysis).
It will burst (lysis).
It will swell and become turgid.
Its shape will remain unchanged.
1. A solution with a higher concentration of solutes than the cell's cytoplasm is called a solution.
2. When an animal cell is placed in a hypertonic solution, it will due to water loss.
3. The pressure exerted by the cell wall on the protoplast in a plant cell is known as pressure.
1. In an isotonic solution, there is no net movement of water into or out of the cell.
True
False
2. Plant cells are more susceptible to lysis than animal cells when placed in a hypotonic solution.
True
False
1. Distinguish between osmosis and diffusion. Provide an example of each.
2. Describe the role of the cell wall in maintaining the turgidity of a plant cell.
Observe the diagram below showing an animal cell in three different solutions. Identify each solution type (A, B, C) and describe the state of the cell in each.
Solution A:
Cell State A:
Solution B:
Cell State B:
Solution C:
Cell State C:
