why do plants need water for photosynthesis

Plants use a complex chemical reaction called photosynthesis to create food from light energy, carbon dioxide from the atmosphere, and water. Each of these performs a critical portion of the photosynthesis process, dependent on the others.

Not only is water used directly in the process of photosynthesis for its hydrogen, it is also used to prevent dehydration, indirectly supporting the successful creation of food for the plant.
