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.
What is the function of stomata and guard cells?
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 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 is the stomata?
---- Stomata are microscopic pores found on the under side of leaves. You will find the stomata in the epidermal tissue. The stomata is bounded by two half moon shaped guard cells that function to vary the width of the pore. Each guard cell contains chloroplasts. The glucose concentration of the the cells changes with the photosynthetic activity and therefore it is the guard cells that regulate the opening and closing of the stoma. ----
Are masses of cells full of pores?
porifera:sponges
What are pores surrounded by guard cells in the epidermis of a leaf?
Stomata are pores surrounded by the guard cells.
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.
Do all plants have guard cells?
yes all plants have guard cells because if there's a plant that don't have guard cells the stomatal pores will not open neither close
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 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 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.
How do guard cells regulate the exchange of gases between a leaf and the air?
The guard cells regulate the exchange of gases between the leaf and air through the use of openings called stomatal pores.
What is the role of guard cell?
Guard cells in epidermis around stomata pores helps in transpiration through stomata and exchange of gases.
How do substances for photosynthesis enter the plant?
Pores called stomata, which open and close by guard cells.
Guard cells open and close pores in leaves to regulate?
Water loss and gas exchange

What is the function of guard cells in regulating transpiration and wilting?
Guard cells play a crucial role in regulating transpiration and preventing wilting in plants. They control the opening and closing of stomata, small pores on the surface of leaves. When the guard cells uptake water, they swell and the stomata open, allowing gas exchange for photosynthesis and transpiration. Conversely, when guard cells lose water, they shrink and close the stomata, preventing excessive water loss and wilting.
