Explanation:
Detailed explanation-1: -All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths.
Detailed explanation-2: -Within the visible spectrum, green leaves have the highest absorptance in the blue region, followed by red. Green light is least absorbed by green leaves, which gives leaves their green appearance (McCree, 1971; Zhen et al., 2019). Figure 1.
Detailed explanation-3: -Blue (420-450nm) and Red (620-680nm): Chlorophyll a is the most abundant pigment in plants. Chlorophyll a absorbs light mostly 430nm (blue) and 662nm (red) wavelength light. It reflects green light so it appears green to us. Chlorophyll b molecule has a similar structure to that of chlorophyll a.
