1.	The figure shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions : (i) At which point(s) A, B or C in the curve, light is a limiting factor ? (ii) What could be the limiting factor(s) in region A ?(iii) What do region C and D represent on the curve ?
Answer» (i) ‘B’ (ii) CO₂ and temperature (iii) ‘C’ represents to constant rate of photosynthesis, ‘D’ is the light saturation intensity at which rate of photosynthesis is maximum.
