Detailed explanation-1: -On a cloudy day the rate of photosynthesis will reduce to less availability of sunlight. As sunlight is the main source of energy in the photosynthetic process.
Detailed explanation-2: -Carbon dioxide level-Photosynthesis can be limited by the level of carbon dioxide. Even if there is plenty of light a plant cannot photosynthesise if it has run out of carbon dioxide. 3. Temperature-If it gets too cold the rate of photosynthesis will slow right down.
Detailed explanation-3: -Could photosynthesis occur in a plant on a cloudy day? Yes Explain: Photosynthesis could occur because some sunlight is able to penetrate the clouds. It would be slower than on a sunny day.
Detailed explanation-4: -(i) The rate of photosynthesis decreases in cloudy day in morning but increases in bright sunshine in the afternoon. (ii) The rate of photosynthesis decreases in the area where there is no rainfall for a considerable time. (iii) The rate of photosynthesis decreases when dust gathers on the leaves.
