Guard cells are specialized cells that surround leaf pores, known as stomata, and play a crucial role in regulating gas exchange and transpiration in plants. By changing their shape, guard cells can open or close the stomata, allowing carbon dioxide to enter for photosynthesis while minimizing water loss. This regulation helps maintain the plant's internal balance and respond to environmental conditions. Ultimately, guard cells are essential for optimizing plant health and efficiency in resource use.
What else can I help you with?
Is a leaf pore a cell?
Yes, leaf pore is a cell, which is also known as stomata.
What are the guard cells in the stomata?
Guard cells are the two curved cells on either side of the pore (hole). By changing their shape they can open or close the pore. When the guard cells absorb water they bend outwards, so that the pore between them opens up. When they lose water they go back to a less curved shape, closing the pore between them. Guard cells bend outwards when they absorb water because the wall next to the pore is thicker than the outer wall, so blah it stretches less. Usually, stomata open in the day to let carbon dioxide into the leaf for photosynthesis and to let oxygen (made by photosynthesis) out of the leaf. They close at night, when photosynthesis cannot take place, to prevent the escape of water. Improved answer- Guard Cell
What will happen to guard cell and stomatal pore when water flows?
When water flows into the guard cells, they become turgid, causing them to swell and curve away from each other. This opening of the guard cells creates an opening of the stomatal pore, allowing for gas exchange and transpiration to occur.
What is the function of a vacuole in a Guard Cell?
Vacuoles in guard cells help regulate the movement of water and ions in and out of the cell, which in turn affects the opening and closing of the stomata. The vacuole can change its volume to control the turgidity of the guard cell, leading to the opening and closing of the stomatal pore for gas exchange.
What leaf structure adjusts the size of the stomata?
Guard cells, which are specialized cells that surround the stomata, are responsible for adjusting the size of the stomatal pore. When the guard cells take up or release water, they change shape and control the opening and closing of the stomata.
Is a leaf pore a cell?
Yes, leaf pore is a cell, which is also known as stomata.
What cell in a leaf are like a balloon?
The guard cell of stomata look like a balloon when it is turgid. Two such cells form the pore of the stomata. When both guard cells of a stomata are deflated by exo-osmosis the stomatal pore is closed.
What are the guard cells in the stomata?

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.
What does a guard cell in stomata contain?
The gaurd cell in the stomata contain chloroplsts and uneven cell wall to create a pore on being turgid.
Are guard cells part of the stomata or does stomata only refer to the pore on the lower surface of the leaf?
The stomata are the pores and the guard cells control the opening and closing of these pores.
What leaf structure adjusts the size of the stomata?
Guard cells, which are specialized cells that surround the stomata, are responsible for adjusting the size of the stomatal pore. When the guard cells take up or release water, they change shape and control the opening and closing of the stomata.
Where leaf pore guard cells found?
They are cells in the leaf epidermis, located arond the stomata. A pair of guard cells open and close each stoma (pore) for gas exchange and transpiration. They are different in shape from the rest of the epidermis cells, and unlike other epidermis cells they also contain chloroplasts.
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).
