Figure 13.10 shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions: (a) At which point/s (A, B or C) in the curve is light a limiting factor? (b) What could be the limiting factor/s in region A? (c) What do C and D represent on the curve? | NCERT solution | Class 11 Biology | Unit-13 Photosynthesis in Higher Plants



Q.8:- Figure 13.10 shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions:

(a) At which point/s (A, B or C) in the curve is light a limiting factor?
(b) What could be the limiting factor/s in region A?
(c) What do C and D represent on the curve?

 

Answer:- 



(a) At point A

(b) Light is a limiting factor also, water, temperature, and the concentration of carbon dioxide could also be limiting factors in the region A.

(c) C represents the stage beyond which light is not a limiting factor. D represents the stage beyond which intensity of light has no effect on the rate of photosynthesis.
