All plants use guard cells to control how long stomata should be opened or closed. CAM plants, for example, close their stomata during the day to prevent loss of water.

If a potted plant is covered with a glass jar water vapour appear on the wall of glass jar Explain why?
Because of transpiration. Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants.
Which part of the leaf enables transpiration to take place?
stomata facilitate transpiration and thick cuticle does not allow it to happen
Why is the stomata at the top for xerophytes?
Xerophytes definitly have their stoma on the BOTTOM of the leaf not the top, this is to minimise water loss through transpiration
What do guard cells close to prevent excess water loss?
The guard cells provide the plant with the control mechanisms. The guard cells control the opening and closing of the stomata in plant tissue. Without guard cells, the plants would not be able to control its water intake.
What is transpires?
Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants. Stoma are "pores" and are generally located on the underside of the leaves of plants.Water accumulating in the leaves of the plants is lost as water vapor through the process of transpiration, this is similar to the process of sweating in animals.Transpiration accomplishes two things, it does cool the leaves slightly through evaporative cooling, it also causes what is referred to as "evaporative draw" or "evaporative suction", this causes a slight low pressure in the leaves where the water is evaporating from, this provides a slight suction force assisting with water being drawn up the stem of the plant.I
What is the process through which is lost through the plants stoma?
transpiration
Which cells in an organism are the sight for respiration in plants?
Transpiration occurs at the stoma.
During which stage of the water cycle does water escape through a plants stoma?
Transpiration.
What is the ''double doors for a stoma?
transpiration
Why cannot transpiration take place in dark?
the sun has to heat up the water in the plants so it can evaporate and exit the stoma
Why do plants close the stomata during the heat of the day?
Stomata, also known as stoma, close in hot weather to retain water. Even though open stoma are necessary for photosynthesis, they can dry out a plant. About 90% of water absorbed by a plant is lost through open stoma. The guard cells close the entrance for protection against dehydration.
What reaction happen in stoma?
photosynthesis and vegetable transpiration.

Because of transpiration. Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants.
Do plants perspire?
yes,yes it can. There are little structures on the bottom of the leaves called stoma or stomata that open and close and let water out. About 90% of a plants water leaves the plant through the stomata. TRY IT: put a plastic bag around some leaves of a plant and make sure it is tied tight, in 24 hrs check your bag and see the results of the prosses called transperation. :)
What is the process through which water is lost through the plant stoma?
transpiration
Function of guard cells?
The guard cells surround each stoma in a plant cell. They regulate the opening and closing of stomata to facilitate gas exchange and control transpiration in plants.
How does acid rain effect things made of metal such as transpiration?
Transpiration it the biological process of the movement of water from roots to stoma through plants. it is not made of metal as it is not a physical entity in itself. Acid rain would probably eat away at things made of metal, and it affects transpiration because it increases the hydrogen ions in the xylem, which increases the cohesion and the rate of transpiration.
