Small opening surrounded by two guard cells and through which moisture and gases pass in and out of the epidermis of a leaf.
A
Force
B
Response
C
Germination
D
Stomata
Explanation: 

Detailed explanation-1: -…the epidermis are paired, chloroplast-containing guard cells, and between each pair is formed a small opening, or pore, called a stoma (plural: stomata).

Detailed explanation-2: -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-3: -Carbon dioxide (CO₂), oxygen (O₂) and water (H₂0) commonly move in or out via the stomata. While gas exchange occurs, carbon (C) stays inside the leaf as a building block for the plant. Often, stomata are open during the day when photosynthesis is taking place and closed at night when it stops.

Detailed explanation-4: -Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.
