A chain of events leads to an increase in the concentration of sugar in the cell sap in the vacuole of guard cell. osmotic potential of cell sap decreases and guard cells withdraw water from the neighboring cells. this increases turgid pressure of the guard cells it swells up.the swelling of the outer wall causes the guard cells to curve away from each other so increases the gap between them stomata opens). and when guard cells lose water, they become flaccid and comes closer thus stomata closes.

. CAM plants close their during the day and open them at night?
stomata
What do cam plants close?
Their stomata during the day!.
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
How do gases enter and leave plants?
In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems. In aquatic plants, gas exchange directly though the tissue surface.
What happens to ordinary plants (or C4 or CAM) when stomata close?
Blah
. CAM plants close their during the day and open them at night?
stomata
CAM plants close their what during the day and open them at night?
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.
What do leaves go through at night?
At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.
Does the stomata close during drought?
The stomata will mostly close during drought. The stomata are responsible for the storage of water in plants. The opening and closing of the stomata regulates the amount of water in plants.
What regulates the stomata?
The guard cells open and close the stomata as needed.
What do plants need stomata for?
To allow gases to diffues in and out of their leaves, down a concentration gradient. Stomata can open and close. This is control by the adjacent guard cells on either side. Stomata will close when it's windy so as not to lose too much water vapour.
What do cam plants close?
Their stomata during the day!.
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
Do all plants have the same amount of stomata?
No, not all plants have the same number of stomata. Stomata numbers vary among different plant species and can be influenced by environmental factors.
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 :)
Would stomata open or close if CO2 concentration decreased?
close
Why do some plants close their stomata at night?
At night, there is no light, therefore no photosynthesis (which is the process of making energy from light). Photosynthesis uses CO2, however since photosynthesis is not occurring at night, there is no need to acquire CO2.Some plants (CAM plants) only open their stomata at night, however, in order to take in CO2 and store it until it is light and they can use photosynthesis then. This helps to eliminate water loss through the stomata which would occur more rapidly if the stomata were open during a hot day. (therefore, most CAM plants are found in desserts and such)
