What is the definition of stomata?

Answer 1

Stomata is the plural form of the word stoma. In regards to plants, stomata are small pores in plant leaves that have cells surrounding them that control the opening and closing of the pore to release gases (oxygen). In anatomy and zoology the word stoma refers to an opening in the body such as the mouth or ears. In medicine, a stoma is an artificial hole created by surgery, as often seen in the throats of long-time smokers who lose their voice-box.

Answer 2

I can't give you the exact scientific definition; but it is a small pore on the underside of a leaf that lets both gases and water (in vapor form) enter and exit the plant.

It is flanked but two cells called 'guard cells' which the plant fills with water in order to open them and allow exchange, or drains them so they close to stop gas exchange and water loss.

Stomata - gap that opens between two guard cells; lets water vapor and gases diffuse across the epidermis of a leaf or primary stem.

Answer 3

Stomata are tiny openings on the surface of plant leaves that allow for gas exchange, including the uptake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They are regulated by guard cells to control the movement of gases and water in and out of the plant.
