Read each question carefully and provide concise answers. Use the diagram provided to answer relevant questions.
1. Define water potential and explain the two main components that contribute to it.
2. How does the movement of water occur in terms of water potential gradients?
Refer to the plant cell diagram below for questions 3 and 4.
3. In a plant cell, what happens when it is placed in a hypotonic solution?
The cell will plasmolyze.
The cell will become turgid.
There will be no net movement of water.
The cell membrane will rupture.
4. Which component of the plant cell prevents it from bursting in a hypotonic solution?
Cell membrane
Vacuole
Cell wall
Cytoplasm
5. Water potential is measured in units of .
6. The addition of solutes to pure water will its water potential.
7. When an animal cell is placed in a hypertonic solution, it will undergo .
8. Pure water has a water potential of zero.
True
False
9. Turgor pressure is the pressure exerted by the cell wall on the protoplast.
True
False
10. Describe the process of osmosis and its significance in living organisms. Include a discussion of isotonic, hypotonic, and hypertonic solutions and their effects on both plant and animal cells.
