网页2024年9月15日 · Stomate, any of the microscopic openings or pores in the epidermis of leaves and young stems. They provide for the exchange of gases between the outside air and the air canals within the leaf. Learn more about stomata and the guard cells that regulate their opening and closing.
Stomata- Structure, Functions, Types & Mechanism of Stomata
网页Stomata are the tiny openings present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis. They control by transpiration rate by opening and closing.
Stoma - Wikipedia
网页In botany, a stoma (pl.: stomata, from Greek στόμα, "mouth"), also called a stomate (pl.: stomates), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere.

网页2017年6月23日 · In plants, a stoma is a tiny pore in the surface of a leaf that is used for gas exchange. Most leaves are covered in these tiny pores, which allow the plants to take in carbon dioxide for use in photosynthesis and expel their waste oxygen. The term “stoma” comes from the Greek word for “mouth.”
