These structures are surrounded by guard cells that allow carbon dioxide to enter and oxygen & water to leave.
A
Stomata
B
Roots
C
Vacuole
D
Chloroplast
Explanation: 

Detailed explanation-1: -A stomate is a pore or aperture surrounded by two guard cells that allow gas exchange. Stomata is the plural term for stomate. Stomata allow for gas exchange to occur, mainly carbon dioxide to enter the plant to make food molecules such as glucose and for oxygen to be released by the plant.

Detailed explanation-2: -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.

Detailed explanation-3: -Guard cells are surrounded by stomatal pores and are located in leaf epidermis.

Detailed explanation-4: -Leaves. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma).

Detailed explanation-5: -Stomata are holes made from spaces between special cells. These holes are where plants absorb carbon dioxide from the air. Once inside the leaf, the carbon dioxide can enter plant cells. Inside the plant cells are special cell parts called chloroplasts, where photosynthesis takes place.
