NEET BIOLOGY

Detailed explanation-1: -So, the correct answer is ‘Chlorophyll concentration’.

Detailed explanation-2: -Oxygen is not a limiting factor as it is never considered as an element required for photosynthesis. It is released as a byproduct during photosynthesis.

Detailed explanation-3: -The absence of oxygen will have no effect on the process of photosynthesis. This is because the photosynthetic process utilises water and carbon dioxide to produce oxygen and carbohydrate in the presence of chlorophyll and sunlight. Thus, oxygen is a product of photosynthesis and is not required for photosynthesis.

Detailed explanation-4: -Answer: The chlorophyll content of leaves, the accumulation of by-products, the internal structure of leaves, light intensity, carbon dioxide concentration, and temperature are the six factors influencing the rate of photosynthesis.
