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 guard cell?
Guard cells, which regulate the opening and closing of stomata in plant leaves, were first described by the botanist Robert Brown in 1827. However, the functional significance of guard cells in gas exchange and water regulation was further elucidated by subsequent researchers. Brown's observations laid the groundwork for understanding the role of guard cells in plant physiology.
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 significance of practice?
To practice to guard yourself in real life situations
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 significance of active transport in a living cell?
It maintains the cell's chemical environment.
What is the significance of diffusion to the cell?
That nutrients are allowed to pass through the cell membrane technically fuel the cell.
