When does plant wilting occur?
Plant wilting often occurs due to a lack of water reaching the plant's cells, causing them to lose turgor pressure and collapse. This can happen when the roots are unable to take up enough water from the soil, leading to dehydration and wilting of the plant. Additionally, factors such as high temperatures, excessive transpiration, or certain diseases can also contribute to plant wilting.
Are guard cell haploid or diploid?
Guard cells are diploid, meaning they have two sets of chromosomes. They are specialized cells found in the epidermis of plant leaves and are involved in regulating gas exchange and transpiration by controlling the opening and closing of stomata.
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 function of bulliform cells?
Bulliform cells are specialized plant cells found in the leaves of grasses and some other monocots. They help in leaf movement by changing the orientation of cells in response to changes in water content, aiding in leaf rolling or folding during dry conditions to reduce water loss through transpiration.
Is wilting a plant's mechanism for survival?
Yes, wilting is a plant's mechanism for survival, primarily as a response to water loss. When a plant experiences drought or insufficient water, it reduces turgor pressure in its cells, causing leaves and stems to droop and conserve moisture. This temporary state helps minimize water loss through transpiration while allowing the plant to endure unfavorable conditions until water becomes available again.

How does wilting on a hot day help a plant?
it helps it by gtowing a new leaf
How do osmosis and transpiration affect wilting?
Osmosis involves the movement of water across a semi-permeable membrane, so in plants, if there is more water outside the cell than inside, water can move out of the cell causing it to wilt. Transpiration is the process where plants lose water through their leaves to the atmosphere, so if transpiration rate is high due to environmental conditions like heat and wind, the plant can wilt faster. Overall, both osmosis and transpiration contribute to the loss of water in plant cells which can lead to wilting if not enough water is taken up from the soil to compensate.
What are the names of the specialized cells that control the aperture of the hole of the stomata?
The specialized cells that control the aperture of the stomata are called guard cells. These cells change shape to open and close the pore of the stomata, thus regulating gas exchange and transpiration in plant leaves.
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
Are guard cell haploid or diploid?

Why does temporary wilting takes place in plants?
the wilting of leaves take place in hot summer days because of excess transpiration.the process of transpiration take place in stomata which is present in leaves of plant.in order to excess transpiration plants wilt their leaves
