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.

What is a Riddle for the word cell membrane?
I am a barrier that surrounds a cell, controlling what goes in and out. I am made up of lipids and proteins, keeping the cell's contents secure. What am I?
What do cell membranes do for the body?
Cell membranes act as a barrier, controlling the movement of substances in and out of the cell. They help maintain cell shape and provide support. Additionally, cell membranes are important for cell communication and recognition.
What does cell membrane do for the animal cell?
It surround the animal cell and keeps it together. It controls the substances passing into and out of the cell.a little more simple form- protects the cell and regulates what goes in and out of the cell. just for all you noobs out there
How would you describe the job of cell membrane?
The cell membrane acts as a protective barrier that surrounds the cell, controlling what enters and exits the cell. It is composed of a lipid bilayer with embedded proteins that help in cell recognition and communication. The cell membrane also plays a role in maintaining cell shape and structure.
What is a cell analogy for a hotel?
A cell can be compared to a hotel where the nucleus is like the hotel manager, controlling activities and storing information. The cytoplasm is similar to the common areas where guests move about and interact. The mitochondria are like the power generators providing energy, and the cell membrane acts as the hotel security, regulating what goes in and out.
What is the function of the cell membrane for kids?
The cell membrane acts like a gatekeeper, controlling what goes in and out of the cell. It also helps the cell maintain its shape and structure. Think of it as the cell's protector, keeping harmful substances out while allowing helpful ones in.
What are the properties and structure of the cell wall that allow it to be selective?
The cell wall decides what goes in and out of a cell
What structure goes around the outside of each plant cell that missing from animal cells?
cell wall

What is the gate?
The official definition for the word gatekeeper is "an attendant at a gate who is employed to control who goes through it."
What is Cell Membrane comparison?
The cell membrane is like a gatekeeper that controls what enters and leaves the cell, similar to a security system. It is flexible and selectively permeable, regulating the passage of molecules in and out of the cell to maintain homeostasis. Additionally, the cell membrane is made up of a phospholipid bilayer with embedded proteins, forming a barrier that separates the internal environment of the cell from the external environment.
A cell membrane is like a what?
A semi-permeable membrane. It could be compared to dialysis tubing.
What does the nucleus do in animal cell?
the nucleus is a dark roundish structure found in the cytoplasm. it controls the cell and regulates everything that goes on inside....
What structure regulates the amount of light that goes into the eye by controlling the size of the pupil?
The iris, which is the colored part of the eye, regulates the amount of light that goes into the eye by controlling the size of the pupil. The muscles in the iris can expand or contract the pupil in response to changes in light intensity.
What is gate keeper?
The official definition for the word gatekeeper is "an attendant at a gate who is employed to control who goes through it."
