Question

It is a lovely summer’s day in John’s greenhouse. Various factors affect the rate of photosynthesis:

PLS EXPLAIN THE QUESTION AND GIVE A WELL EXPLAINED ANSWER

Answer 1

Explanation:

Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply.

Answer 2

Answer:

temperature

Explanation:

tomato is a c₃ plant in all other factors it show higher optimum level than c₄ plants but in case of temperature , optimum level is 20-25⁰c  ie: comparitively low .
