When plant cells are in a hypotonic medium, they (a) undergo plasmolysis (b) build up turgor pressure (c) wilt (d) decrease pinocytosis (e) lose water to the environment
1. Estimate the maximum turgor pressures (Ψp) inside the cells of leaves and flowers.
2. Which structure (leaves or flowers) have stiffer, more rigid cell walls? What part(s) of the graphs tell you this?
3. At about what relative cell volume (equal to relative water content) does incipient plasmolysis occur for each structure?
4. Which structure (leaves or flowers) has more solutes inside the cells?
5. Which structure (leaves or flowers) do you expect to undergo more shrinking and swelling in volume with changes in water content?
6. Imagine you wanted to display a C. speciosa shoot in a vase in your house. You cut a flowering shoot (a shoot with both leaves and flowers on it) from a tree growing outside. You then transport the shoot into your house. As you carry it, the leaves and flowers are evaporating water. By the time you place the shoot in the vase of water, the relative water content (equivalent to relative cell volume) of the leaves and flowers has declined to…
