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.
What is the cell that makes up the stoma?
The two guard cells one either side contract to open and close stoma.
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.
Guard cells open and close stomates to prevent?
carbondioxide
What cell is used to open and close the stoma?

What structures open or close the stomata?
the guard cells
Stomata open and close in response to pressure within?
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.

What will happen to guard cell and stomatal pore when water flows?
The guard cell swell when water flows into them,causing stomatal pore to open.
