Answer: small openings tha penetrate though the epidermis called stomata exist
useually on the lower surface of the leaf. the water lilly is an example of
a plant that has the stomata on the upper surface of the leaf. these
stomates allow air (CO2) to circulate through the inner portions of the
leaf and enter the photosynthetic pathways
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.
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 allow a plant to take in carbon dioxide which is needed for photosynthesis.

Stomata (singular stoma) are tiny openings or pores found in the epidermis of leaves and young stems that helps in gas exchange. Pair of specialized bean-shaped cells called guard cells are found to surround each stoma. Just like animals breathe plants do so with the help of stomata. Under the microscope they appear dense or dark.
Stomate also called stoma plural stomata or stomas any of the microscopic openings or pores in the epidermis of leaves and young stems. Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf.
In botany a stoma (from Greek στόμα "mouth" plural "stomata") also called a stomate (plural "stomates") is a pore found in the epidermis of leaves stems and other organs that controls the rate of gas ex...
