What is the role of a stomata and guard cells?
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
What does guard cells do on a leaf?
Control the opening and closing of the stomata.
Which do guard cells control?
excess water loss
What cells regulate the amount of water vapor that passes through the stoma?
A stoma is simply the space between two cells called guard cells.The guard cells are specialized cells of the leaf's epidermis. The guard cells have unevenly thickened walls. When their vacuoles contain the maximum amount of water, turgor causes the cells to bend, leaving a space, the stoma, between them.When the osmotic pressure falls, the cells partially collapse, like partly-deflated balloons, closing the stoma.The variations in turgor in guard cells are brought about by varying concentrations of potassium ions in the cells.
How the opening and closing of leaf stomata is controlled?
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
Is the specialized structure that surrounds the stomata on the underside of leaves?
guard cells
Guard cells surround and control the opening of the?
Stomata
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 is the role of a stomata and guard cells?

What are formed by two specialized epidermal celled guard cells?
Stoma ( singular) and its plural is stomata
What does guard cells do on a leaf?
Control the opening and closing of the stomata.
Is Stomata and mitochondria are two specialized cells found only in plants?
stomata are found only in plants cells, but mitochondria are in both plant and animal cells. remember, they both perform cellular respiration, which occurs in the mitochondria
To control water loss the size of the stomata is reduced by the?
Guard Cells
Which do guard cells control?
excess water loss
What cells of the epidermis control sizes of stomata?

What is the relationship between guard cells and stomata?
Guard cells are cells on the edges of the stomata of a leaf. The stomata are very small pores that control water loss and keep the plant from drying out. When Abscisic Acid (ABA) - a stress hormone - is present, the Potassium ions (K+ ions) from the guard cells leave the guard cells for an unknown reason. This causes the stomata to close. Basically, guard cells assist stomata in opening/closing
What is the cell that conrols the gases going into and leaving a leaf?
Plants have pores on the underside of the leave called stomata (or stoma in singular). By opening or closing these pores, they allow the oxygen formed inside the plant to exit, and the carbon dioxide outside to enter.
