∙ 13y agostomata open or close in response to light. they function in gas exchange in plants. usually open during the day. The opening and closing of a stoma is controlled by guard cells, a pair of crescent-shaped cells that surround the pore opening. A stoma opens when guard cells absorb watter, and closes when they lose water.

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.
What does guard cells do on a leaf?
Control the opening and closing of the stomata.
How does turgor pressure affects the opening and closing of stomata?
The stoma is "turgor operated valve". The opening and closing of stoma is regulated by the turgidity of guard cells. The stomata are open when the guard cells are turgid. On losing turgidity in guard cells, the stomata closes.
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.
Light and carbon dioxide and what all affect the opening and closing of stomata?
Choloroplasts in the gaurd cell and availability of Water.
What ions involve the opening and closing of stomata?
Potassium ions, they contribute to the control of turgidity of guard cells, and thus the opening and closing of stomata.
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.
Does a Stomata control opening and closing of the openings in the leaf?
A stomata is the openings in the leaf.
What does the guard do?
Gaurd cells help in opening and closing of stomata
What does guard cells do on a leaf?
Control the opening and closing of the stomata.
Cells that form edges of the stomata?
Guard cells. They are bean-shaped and this allows for the opening and closing of stomata.
What is the function of a guard cell and when they open?
To regulate opening and closing of stomata
What is role of potassium ions in photosynthesis?
It controls opening and closing of stomata .
What does the guard cell?
Gaurd cells help in opening and closing of stomata
How does turgor pressure affects the opening and closing of stomata?
The stoma is "turgor operated valve". The opening and closing of stoma is regulated by the turgidity of guard cells. The stomata are open when the guard cells are turgid. On losing turgidity in guard cells, the stomata closes.
What are the cells the guard the stomata?
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.
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.
