Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The tiny openings on the surface of the leaf are called
A
cuticle
B
stomata
C
dermis
D
guard cell
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Detailed explanation-3: -Stomata are cell structures in the epidermis of tree leaves and needles that are involved in the exchange of carbon dioxide and water between plants and the atmosphere. From: Introduction to Forestry and Natural Resources, 2013.

Detailed explanation-4: -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.

Detailed explanation-5: -Stomata are pores on the leaf surface, which are formed by a pair of curved, tubular guard cells; an increase in turgor pressure deforms the guard cells, resulting in the opening of the stomata.
