By closing the stomata of the plant during times when water is in short supply, there will be decreased transpiration. Transpiration is the movement of water through the plant as well as it's evaporation rate.

∙ 13y agoWhen the stomata opens the guard cells become turgid, and when the stomata closes it becomes flaccid. How does that happen? When light (blue) hits the stomata it causes the hydrogen channels to open. Hydrogen is pumped in response to increased blue light levels. In response to hydrogen moving out potassium moves in, and water follows, which increases turgor pressure.
At night what happens is that there is no blue light to cause the stomata to open therefore it closes.

What plants close stoma to control transpiration?
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.
Where does gas exchange and water loss occur in plants?
By opening and closing the stomata on the underside of the leaves.
Why does having too much stomata increase water loss?
Stomata are like pores that are meant to control water levels, especially in transpiration. The right number of stomata keeps the plant in equilibrium, too many and the plant loses too much water, drying out and dying.
How is the lost water in stomata replaced?
The guard cells of the stomata have greater osmotic pressure due to loss of water. Thus, by way of osmosis this loss is compansated continuously from the surrounding cells of the stomata.
How does a plant manages the conflict between the loss of water through transpiration and the need for C02 for photosynthesis?
By putting control over opening and closing of stomata and also creating the devices to minimize the loss of water by transpiration, such as position of stomata on the lower surface of leaf, away from sunlight, presence of hairs and sunken stomata etc.
What plants close stoma to control transpiration?
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.
Where does water plants have stomata?
to prevent excessive water loss by transpiration
Is the loss of water from plants?
Plants lose most of their water by transpiration through the stomata of the leaves.
What is the importance of guard cells?
If by guard cells you mean the ones located in plants, they open and close the stomata to control water loss :)
To control water loss the size of the stomata is reduced by the?
Guard Cells
Which do guard cells control?
excess water loss
Why don't plants keep their stomata open all time?
Plants don't keep their Stomata open all the time to prevent too much water loss.
Why don't plants keep their stomata open all the time?
Plants don't keep their Stomata open all the time to prevent too much water loss.
What is the loss of water from plants called?
Transpiration is water loss from plants.
What is transpiraton?
The loss of water from the aerial parts of the plants specially through the stomata is known as the "Transpiration".
Where does gas exchange and water loss occur in plants?
By opening and closing the stomata on the underside of the leaves.
Do desert plants or rain forest plants have more stomata?
Yes They Do. This is because the plants in desert plants need to retain as much moisture as possible. The plants in the forest don't because its moist enough. So the plants in the forest have more stomata then plants in the desert.
