What enables guard cells to close and open?
I think it is Cell membrane
How plants open and close the stomata?
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.
Which structure is a gatekeeper controlling what goes in and out of the 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.
What causes a stomata to open and close?
Stomata open due to a decrease in water content inside guard cells, causing them to become turgid and curve outward. This creates an opening for gas exchange. Stomata close when the water content in guard cells increases, causing them to become limp and close the opening to prevent water loss.
Guard cells open and close pores in leaves to regulate?
Water loss and gas exchange

What structures open or close the stomata?
the guard cells
What is the significance of a guard cell?
Guard cells open or close to increase or decrease the rate of transpiration. They help the plant to adapt to varying environmental conditions such as changes in temperature, light, humidity, or soil moisture.
How do guard cells work?
Guard cells work to open the stomata of plant leaves, which fosters the exchange of gas and lets out transpired air (evaporated from the apoplast of the leaf). They do this in response to sunlight hitting the leaves, by pumping K+ (Potassium) ions in to create a more negative solute potential inside the guard cell; water follows the K+ ions in to equalize the water potential. With the extra water, the guard cell turgidity increases and the 'puffed up' guard cells cause the stomata to open.

Stomata open and close in response to pressure within?
Stomata open and close in response to changes in turgor pressure within the guard cells. When guard cells take up water, they become turgid and the stomata open to allow gas exchange. Conversely, when guard cells lose water, they become flaccid and the stomata close to prevent water loss.
The type of cell that controls the opening and closing of stomata is called?
guard cells
What regulates the stomata?
The guard cells open and close the stomata as needed.
What is the function of a guard cell and when they open?
To regulate opening and closing of stomata
