Guard cells play a crucial role in regulating transpiration and preventing wilting in plants. They control the opening and closing of stomata, small pores on the surface of leaves. When the guard cells uptake water, they swell and the stomata open, allowing gas exchange for photosynthesis and transpiration. Conversely, when guard cells lose water, they shrink and close the stomata, preventing excessive water loss and wilting.

When does plant wilting occur?
Plant wilting occurs after excessive loss of water by transpiration and lesser absorption by the roots. The deficiency of water in the cells make them flaccid and the plant wilts.
Why does a plant have different cells?
As in animals, plant cells have specialized functions such as water absorption (roots), photosynthesis (chloroplasts), and transpiration (guard cells). The shape, size, and composition of each cell has to provide the necessary characteristics for its function.
What is the relationship between stomata and photosynthesis?
stomate are opening on the underside of a leaf. They are controlled by guard cells. When guard cells are turgid they stomate open and transpiration occurs when they are flaccid they close to retain water and prevent loss of water by transpiration
Why are the guard cells in the lower epidermis the only cells with chloroplasts in a leaf?
Guard cells in the lower epidermis are the only cells with chloroplasts in a leaf because they play a crucial role in regulating gas exchange and water loss through the stomata. Chloroplasts allow guard cells to photosynthesize and produce sugars, which provide the energy needed for stomata opening and closing. This specialization ensures efficient control over transpiration and photosynthesis in leaves.
What is the function of T-cells?
this is my question what is the function of t-cells?
When does plant wilting occur?
Plant wilting occurs after excessive loss of water by transpiration and lesser absorption by the roots. The deficiency of water in the cells make them flaccid and the plant wilts.
How does wilting on a hot day help a plant?
it helps it by gtowing a new leaf
Why do plants wilt shortly after watered?
During day time when transpiration occurs watering of plants removes the air from the soil and in the abscence of oxygen root cells can not respire aerobically, hence uptake of water is affected. When the loss of water due to transpiration is not compensated by absorption of water by the roots, wilting is observed in these plants.
What is the function of a guard cell in plants?
The function of the guard cells are that they help to regulate the rate of transpiration by opening and closing the stomata thus preventing excessive water loss.
What is the guard cells in a plant cell?
The function of the guard cells are that they help to regulate the rate of transpiration by opening and closing the stomata thus preventing excessive water loss.
Which structure controls transpiration?
guard cells

Where transpiration take place?
plant cells
Where does transpiration take place?
plant cells
What is the function of the guard cells in regulating gas exchange in a leaf?
The stoma opens and closes to allow gas exchange. The Guard cells are located around the stoma and regulate the opening and closing of the stoma.
Is water released from plant cells through the process of transpiration?
Yes
Which cells in an organism are the sight for respiration in plants?
Transpiration occurs at the stoma.
