I got this question in an internship interview.

I want to ask this question from Factors Affecting Photosynthesis in division Photosynthesis in Higher Plants of Biology – Class 11

Answer 1

Right choice is (a) The leaf orientation of a plant affects photosynthesis

Best explanation: The rate of photosynthesis is affected by both external and internal factors. The photosynthetic rate is determined by a factor at sub-optimal level which is known as the limiting factor.
