Answer:
(A) Enters plant as a part of water
Explanation:
Molecule of water is made up of hydrogen and oxygen.
During photosynthesis, water is part of the resources needed by green plants to manufacture their food with the aid of sunlight.
During the process of photosynthesis, water goes into the plant and is split into hydrogen and oxygen. Hydrogen gotten from the splitting of water molecules is used for manufacturing organic compounds that serve as as a source of chemical energy and food for the plant, while oxygen is given off and removed from the plant as by-product.
