To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight.

Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf.
During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss.
There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.
What else can I help you with?
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
What are the cells that surround the stomata called?
Guard Cells surround the stomata, and enable it to open or shut.
. CAM plants close their during the day and open them at night?
stomata
Which cells form the stomata?
Guard cells form the stomata. They can open and close to regulate the exchange of gases such as oxygen and carbon dioxide, as well as control water loss in plants.
Does the stomata on a leaf have to be open or closed during the Calvin benson cycle?
The stomata better be open so that plenty of carbon dioxide diffuses into the leaf and feeds into the Calvin cycle and makes sugars, specifically glyceraldehyde-3-phosphate.
What regulates the stomata?
The guard cells open and close the stomata as needed.
Why do a leafs stomata open and close?

The stomata of leaves are usually open in?
in the day
What causes the stomata on leaves open?
Daylight
Why do stomata's need to be open?
To maintain homosigius
Does a cacti open its stomata during the day?
no!
How does a plant get its gas needs for photosynthesis?
the stomata open
What structures open or close the stomata?
the guard cells
Water vapor moves out of leaves through open stomata This process is known as?
Transpiration
Why do leaves stomata shut at night?
They shut because with the stomata open it is too drafty and the plant can't get to sleep.
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.
What causes the stomata on leaves to open?
Stomata open in response to environmental factors such as light intensity, CO2 levels, and humidity. Light triggers the production of a hormone called abscisic acid, causing the guard cells around the stomata to swell and open. Conversely, in darkness or when environmental conditions are unfavorable, the stomata close to prevent water loss through transpiration.
