Figure 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?
Light intensity and photosynthesis rate graph
(a) In the given graph, light serves as a limiting factor where photosynthesis occurs to the lowest degree. As a result, light is limiting at point A.
(b) Light can limit the growth of plants; water, temperature, and carbon dioxide concentration are also factors.
(c) At stage C, light is no longer a limiting variable. Photosynthesis has already reached its highest rate at point D when light intensity no longer affects photosynthesis.Answered by Abhisek | 1 year ago
