Vedclass · Answer

(B) The rate of photosynthesis and subsequent plant growth is primarily dependent on the absorption of light by chlorophyll pigments. Chlorophyll $a$ and $b$ show maximum absorption peaks in the blue and red regions of the visible light spectrum. Among these,red light is particularly effective in promoting vegetative growth and stem elongation,while blue light is essential for stomatal opening and phototropism. Therefore,maximum growth is observed under red light conditions.
