How does a Stomata help a plant ?
A stomata helps a plant by oxygen exiting through the
stomata on the underside of the leaf. A stomata helps a plant by small
openings on the underside of the leaf which oxygen and carbon dioxide
can move .

stomata occur on all living plant parts that have contacts with the air
they are especially abundant on leaves.
A single leaf may have many thousands of stomata. The stomata
can function normally, the carbon dioxide and water within the plant , in the presence of sunlight, manufacture sugars stores starches for later use, and exhales pure oxygen.
A stomata is a pore found in the leaf and stem epidermis that is used
for gas exchange.
Air containing carbon dioxide and oxygen enters the plant through these
openings where it is used in photosynthesis and respiration respectively.
Oxygen produced by photosynthesis in the spongy layer cells of the leaf
exits through these same openings. Also water vapor is released
into the atmosphere through these pores in a process called transpiration.
