Stomata: Definition, Types, Structure, & Function - Science Facts
2023年2月3日 · Stomata are tiny pores mainly found on the lower epidermis of the leaf, which allow gas exchange in plants. In contrast, guard cells are pairs of bean-shaped cells surrounding each stoma, which controls pores’ opening and closing.
Stomate | Definition, Function, Description, Structure,
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.
Stoma - Wikipedia
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.

2024年9月7日 · Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores.
Stomata – Definition, Structure, Mechanism, Functions
2024年11月1日 · Stomata are tiny pores located on the epidermis of plant leaves and stems that regulate gas exchange, allowing carbon dioxide, oxygen, and water vapor to enter and exit the plant. Each stoma is flanked by guard cells that control its opening and closing, facilitating processes such as photosynthesis and transpiration.
