If the water potential in a leaf is -0.3MPa, what will the water potential of the guard cells be as the stomata opens?
Homework Answers
As we know that stomata opens due to turgidity of guard cell .This turgidity happens due coming of water inside the guard cell.As we know that water moves from high water potential to low water potential, hence THE POTENTIAL OF WATER SHOULD BE LESS THAN IN THE LEAF.i.e. -0.3 Mpa.
I.e. more negative than -0.3Mpa.

In transpiration, water exits the leaves through the (guard cell / stomata ). When guard cells are turgid a plant's stomata open, when guard cells are flaccid a plant's stomata are closed. True False

How are the functions of stomata and guard cells related and what would be the consequence if those cells did not function property? Select one: a. Guard cells are responsible for opening and closing the stomata, and if the stomata did not function then gas exchange and transpiration will not occur through these cells b. Guard cells are responsible for opening and closing of the stomata, and if the guard cells did not function then gas exchange and transpiration will...

When placed in water, wilted plants regain their leaf turgor because of the active transport of salts from the water into the plant cells. osmosis of water into the plant cells. osmosis of water out of the plant cells. diffusion of water out of the plant cells. active transport of salts from the plant cells into the water.

Plant water relations overview We use the term water potential (Ψw) to describe the chemical potential of water, and our understanding of diffusion of water depends on our understanding of how various factors (such as temperature, pressure, presence of dissolved solutes) affect the water potential in various parts of a system. Since diffusion of a substance tends to occur downward along a chemical potential or free energy gradient, it also is important to understand how such gradients are established. By...

How does this minimize water loss by such plants? How does this minimize water loss by such plants? A. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through open stomata thereby is minimized. During the day, when solar energy is available but the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle. B....
