In grammatically correct sentences trace the path of the products of photosynthesis as they exit the leaf.

The correct answer is -

O2 - through the stomata

Glucose - through the phloem in the veins

H2O- through stomata

Explanation:

In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.

These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.
