Answer to Question #23353 in Other Biology for Rabiya
suggest what will be the rate of photosynthesis in the absence of water/carbon dioxide?
A shortage of water does affect the rate at which photosynthesis occurs. Lack of water also impacts the quantity of carbon dioxide available for photosynthesis. This is because in response to the drying of leaves plants close their stomata in order to conserve water being lost as water vapor through them. Carbon dioxide is essential for the light reactions in all plants that carry on photosynthesis. However, it has been determined that 0,1% of carbon dioxide in the atmosphere increases the rate of photosynthesis significantly.
