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…
2) Name and describe the three types of compartments found in plants in terms of water relations. How do these relate to the three different routes that an ion can take as it moves from the soil and through plant tissue?
In plants, water is transported through vessels called xylern. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues ? Root hairs push water through the roots and up into the xylem. Plants absorb water through transpiration to supply their upper tissues with water . С The guard cells surrounding the stomata expand and contract, pushing water through the xylem. Water escapes from the leaves through transpiration, creating a vacuum which pulls water up the xylem.
Which the following statement is FALSE:?a. Relative water content is not a very sensitive index because leaves can show strong responses to <2% change in RWCb. Relative water content is not a very sensitive index because it gives no information about the forces for water movementc. Relative water content is equal the ratio of the mass of water in a given leaf over the mass of water when that leaf was fully saturatedd. Relative water content is equal the ratio of the mass of water in a dry leaf over the mass of water when that leaf was fully saturated
You place a flaccid plant cell (Ψ = -0.7 MPa) into an environment (beaker) of pure (deionized) water (Ψ = 0 MPa). Compare the initial conditions of the flaccid cell and the environment (beaker of pure water) in terms of: G) Predict the direction of water movement (into the cell, out of the cell, or no net movement) H) Predict the change in turgor pressor of the cell (increase turgor pressure or decrease turgor pressure) I) Predict the fate of the cell (plasmolyzed, turgid, or lysed)
