Answer:
D
Step-by-step explanation:
Carbon dioxide enters through the stomata on the underside of the leaf.
Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).
Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.
