Answer:
The correct answer is "Oxygen is released into the atmosphere through stomata."
Step-by-step explanation:
A plant needs water, (H₂O) carbon dioxide, (CO₂) and light energy to produce food that is oxygen (O₂) and glucose through a process known as "photosynthesis".
Water + Carbon dioxide + Light energy = Oxygen + Glucose
In the attached diagram, it is shown that plant releases oxygen into the atmosphere through the leaves (stomata).
The stomata controls the flow of oxygen and carbon dioxide into and out of the plant whereas xylem is used for the transportation of water from the roots to the leaves in the plant.
The process of photosynthesis only happens when the light is present, plants have a pigment named "chlorophyll" which absorbs the light energy.
