    Water is considered one of the most important factors affecting photosynthesis. When there is a reduced water intake or availability, the stomata begin to close to avoid loss of any water during transpiration. With the stomata closing down the CO2 intake also stops which affects photosynthesis. Therefore, the effect of water on photosynthesis is more indirect than direct.
