In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") (from Greekστόμα, "mouth"), is a pore, found in the epidermis of leaves, stems, and other organs, that is used to control gas exchange.
The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the opening. The term is also used collectively to refer to an entire stomatal complex, both the pore itself and its accompanying guard cells. Air enters the plant through these openings, and contains carbon dioxide and oxygen, which are used in photosynthesis and respiration, respectively. Oxygen produced as a by-product of photosynthesis diffuses out to the atmosphere through these same openings. Also, water vapor is released into the atmosphere through these pores in a process called transpiration.
Stomata are present in the sporophyte generation of all land plant groups except liverworts. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. Monocotyledons, on the other hand, usually have the same number of stomata on the two epidermes. In plants with floating leaves, stomata may be found only on the upper epidermis and submerged leaves may lack stomata entirely.

Stomata :
Stomata (the word stomata means "mouth") are small pores found in the leaves of the plant that helps in gaseous exchange during photosynthesis and respiration. Stomata consist of two types of cells, the stoma or the pore and guard cells. Stomata are guarded pair of crescent shaped specialized parenchyma cells called guard cells which regulates the size of opening or pore of stomata.

GCSE Biology - Structure of a Leaf and Stomata #50
In this video we cover how plants are organised, and then take a closer look at the leaf. We consider the different parts of a leaf and how it is adapted for its functions.
We re-uploaded this video as the original had some unedited footage left in it. Sorry!

Scientists from Nagoya University have discovered a novel regulatory mechanism that controls the opening of stomata in plants, which is crucial for harnessing solar energy through photosynthesis.
Stomata are vital for regulating water and carbon dioxide in plants, affecting photosynthesis ... This paper introduces DeepRSD, a deep learning-based method designed to detect rotating stomata and calculate their traits.
Plants have tiny holes on the underside of their leaves called stomata which essentially do the same thing. (Stomata is a plural word, the singular form is stoma.) When the stomata open, water vapor is released, thereby helping to cool the plant.
