The Guard cells
guard cell, vacuole, chloroplast, cell wall, stoma, nucleus etc
Stoma, also referred to as stornate or stornata (plural).
A stoma comprise of two cells, called gaurd cells. Each of these gaurd cellwall is thick around the pore, so when gaurd cells are swollen, these bend towards the pore making the stoma open. The bending happens due to turgidity of gaurd cell and their unequal thickness of cell wall.
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".

It's actually the guard cells. Water vapor does go through it, though.
