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.
What role does potassium play in guard cell movement?
Potassium plays a crucial role in guard cell movement by regulating the opening and closing of stomata, which are small pores on plant leaves. When potassium ions (K+) are actively transported into guard cells, it causes water to enter the cells through osmosis, leading to swelling and the opening of the stomata. Conversely, when potassium is removed from the cells, water exits, resulting in cell shrinkage and stomatal closure. This process is vital for gas exchange and transpiration regulation in plants.
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 plays a role in cell division?
Nuclear division plays a role in cell division.
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.
In what cell does most photosynthesis happen?
guard cell and palliside cell

What is role of two guards in basketball?
point guard and shooting guard
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.

prison guard
What controls the size the stoma?
a guard cell.

the cell will died
What is the purpose of the guard cell in a plant?
for exchange of gases
