Gaurd cells help in opening and closing of stomata
What else can I help you with?
Is a guard cell a tissue a organ or a cell?
A guard cell is a type of cell found in the epidermis of plant leaves. It is not a tissue or an organ; rather, it is a specialized cell responsible for regulating the opening and closing of stomata to control gas exchange and water loss in plants.
In what cell does most photosynthesis happen?
guard cell and palliside cell
When a potassium ion (K ) enters a guard cell it creates a solution of?
When a potassium ion (K+) enters a guard cell, it creates a solution with a higher osmotic potential inside the cell than outside. This influx of K+ ions increases the osmotic pressure within the guard cell and leads to the uptake of water, causing the guard cell to swell and ultimately leading to stomatal opening.
What is the controls the movement into and out of cell?
prison guard
What controls the size the stoma?
a guard cell.
What would happen if the cell of a developing plant did not differentiate into guard cells?
the cell will died
What is the purpose of the guard cell in a plant?
for exchange of gases
The scientific name for a guard cell?
The scientific name for a guard cell is stoma guard cell. These specialized cells are located in the epidermis of plant leaves and regulate the opening and closing of stomata to control gas exchange and water loss.
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.
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 cell is used to open and close the stoma?
The Guard cells
What is the difference between a human nerve cell and plant guard cell?
A human nerve cell is a specialized cell in the nervous system that transmits electrical signals, while a plant guard cell is a specialized cell in plants responsible for regulating gas exchange and water loss through openings called stomata. Nerve cells are found in animal tissues, while guard cells are unique to plants.
