How does carbon dioxide,water and light affect the process of photosynthesis?
As we know, photosynthesis is a process of synthesis of food (glucose) by green plants in the chlorophyll in the presence of sunlight and carbon dioxide. Also, plants require water for their survival.
1. carbon dioxide: Carbon dioxide normally present is atmosphere is about 0.039% If the level of carbon dioxide in the environment increases, the rate of photosynthesis increases. But if the level of carbon dioxide increases very much, it may become toxic and rate of photosynthesis decreases. If the concentration of carbon dioxide decreases, the rate of photosynthesis decreases.
2. Water: It is indirectly required for the process of photosynthesis as plants require it to maintain their temperature and carry other metabolic activities. Water also controls the opening and closing of stomata. If concentration of water decreases, the rate of photosynthesis decreases.
3. Light: If the light intensity and duration increases, the rate of photosynthesis increases but if it increases too much, it may damage or wither the plant. Also, it depends upon the type of plants as some plants grow in high light intensity and duration while some in low.
