How Water Is Used in Photosynthesis?

All green plants use photosynthesis to live.

Plants use the process of photosynthesis to convert sunlight into sugar and oxygen. Then, the sugar converts to adenosine triphosphate (ATP), which fuels the plant. Photosynthesis allows a plant to live and grow.

Significance

Photosynthesis cannot occur without water. When deprived of water, a plant will wither. Eventually a water-deprived plant will die because it cannot manufacture energy to sustain life.

Function

Photosynthesis requires water. When six water molecules join with six carbon dioxide molecules, a chemical reaction occurs that changes the molecules into sugar.

Process

The plant's roots absorb water from the ground. The xylem plant cells then transport the water throughout the plant. Photosynthesis takes place in the chloroplasts of the plant.
