It's actually the guard cells. Water vapor does go through it, though.
The size of the stomatal opening is primarily regulated by guard cells, which respond to environmental signals like light, humidity, and carbon dioxide levels. When water enters the guard cells, they swell and cause the stomatal pore to open. Conversely, when water leaves the guard cells, they become flaccid, leading to stomatal closure.
The Nucleus controls the cell.
the nucleus controls all the activity in the cell.
The plasma membrane controls the passage of nutrients into the cell and wastes out of the cell through a process called selective permeability. This involves transport proteins and channels that regulate the movement of molecules based on size, charge, and concentration gradients.
The "stoma" is found in the outer layer of the leaf(epidemis), it allows the passage of oxygen to the environment. The plural of "stoma" is "stomata".
a guard cell.
Well if your thinking about were all items enter and exit is through the stoma. The nucleus is the brain of the cell though and controls everything.
There are two guard cells on each stomate. They can open and close the pathway.
Stoma of the leaf.
Guard cells make up the stoma
Stomata for plural, and stoma for singular... Stoma/stomata is a guard cell and it also serves as an opening. source: Biology class... ^^,

In a palisade cell, the nucleus is responsible for storing and managing genetic information in the form of DNA. It controls the cell's activities, including growth, metabolism, and reproduction. Additionally, the nucleus regulates protein synthesis and controls gene expression to support the functions of the cell.
The Nucleus controls the cell.
cytoplast cell it controls a substance into and out a cell.
the cell membrane controls what goes in and out the cell
