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.

Guard cells open and close stomates to prevent?
carbondioxide
Under what conditions would the guard cells close the stomates?
To prevent excess water loss through transpiration - normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.
What is the relationship between stomata and photosynthesis?
stomate are opening on the underside of a leaf. They are controlled by guard cells. When guard cells are turgid they stomate open and transpiration occurs when they are flaccid they close to retain water and prevent loss of water by transpiration
Do all plants have guard cells?
yes all plants have guard cells because if there's a plant that don't have guard cells the stomatal pores will not open neither close
Shannon is a botanist who observed stomatal closing of plants under daytime drought conditions Why would the stomata close?
To prevent loss of water from guard cells
Guard cells close the to prevent excess water loss?
stomata

What cells guard the opening and closing of the stomata?
Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. Guard cells and adjacent subsidiary cells are involved in opening and closing of stomata.
Stomata open and close in response to pressure within?
guard cells
What is the gatekeeper cell?
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
Which do guard cells control?
excess water loss
What is the relationship between stomata and photosynthesis?
stomate are opening on the underside of a leaf. They are controlled by guard cells. When guard cells are turgid they stomate open and transpiration occurs when they are flaccid they close to retain water and prevent loss of water by transpiration
Is it true that guard cells of non desert plants often close during the daytime and open at night to conserve water?
The guard cells of non desert plants simply contract a bit but do not close. Desert plants close their guard cells.
Can guard cells carry out photosynthesis?
No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated
When would guard cells close the stomates?
Guard cells would close the stomata to prevent excess water loss through transpiration, normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.
What structures open or close the stomata?
the guard cells
