That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
The cell membrane acts as a gate keeper. The cell membrane is selectively permeable which controls the movement in and out of the cell.
It is a cell that can keep your brain from sensing or detect pain.
The cell structure that is the gatekeeper in a cell is called the cell membrane.
The cell membrane acts as the gatekeeper of the cell, determining what goes in or out.

They protect and hold the cells together. It controles wht goes in and out of the cell.
The cell membrane. However, a plant's cell wall is rigid while the cell membrane is not. Plant cells also have a cell membrane.The cell membrane protects the cell and holds it together.(Plant cells have them too, however. One of their main functions is to regulate what comes in and goes out of the cell).

the nucleus is a dark roundish structure found in the cytoplasm. it controls the cell and regulates everything that goes on inside....
The official definition for the word gatekeeper is "an attendant at a gate who is employed to control who goes through it."
All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.

An animal cell has a cell membrane. It controls what goes into and out of the cell. Plant cells on the other hand have cell walls which protect the cell and give it its ridged structure. that is why plants are harder than animals.
A cnidoblast is the harpoon like structure of a jellyfish and a nematocyst is the stinging cell
They protect and hold the cells together. It controles wht goes in and out of the cell.
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
