Question

Why does C4 photosynthesis result in less water loss than C3 photosynthesis?

Answer 1

Question

C4 photosynthesis result in less water loss than C3 photosynthesis because C4 plants while performing photosynthesis can keep their stomata closed as compare to the C3 plants because C4 plants are more efficient in incorporating carbon-dioxide. So, for less time stomata are open in case of C4 plants for the carbon-dioxide and oxygen exchange and plant losses less water due to transpiration through which water get loss. The C4 plants anatomy, is more efficient as they do not allow photorespiration to take place and thus highly capable of fixing of carbon-dioxide.
