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 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.
Fwho first discovered cell and that year was he born?
The cell was first discovered by Robert Hooke in 1665. He was born in 1635.
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 is the cell membrane referred to?
Plasma membrane.The cell membrane also called the plasma membrane or plasmalemma is the biological membrane separating the interior of a cell from the outside environment.
Was the first cell ever discovered the cork cell?
Well that was the fist discovered cell membrane
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
Who discovered the cell wall in the cell?
Rober Hook first observed the cell.So he also discovered the cell wall.
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 cell Robert brown discovered?
He discovered the cell nucleus within cells as one of his major accomplishments
What will happen to guard cell and stomatal pore when water flows?
When water flows into the guard cells, they become turgid, causing them to swell and curve away from each other. This opening of the guard cells creates an opening of the stomatal pore, allowing for gas exchange and transpiration to occur.
Who discovered the first cell?
it was discovered by Robert HookRobert hook
Where was the mitochondria discovered?
in a cell.
What is the controls the movement into and out of cell?
prison guard
What controls the size the stoma?
a guard cell.
What is a metaphor for a cell wall?
A cell wall can be metaphorically compared to a protective fortress surrounding a city, providing structural support and defense against external threats while allowing controlled passage of materials in and out.
