Detailed explanation-1: -Chlorophyll absorbs all colors present in VIBGYOR except the green color. The highest absorption occurs in violet-blue and red regions of visible light. Pigment chlorophyll is present in the chloroplast of the cells.

Detailed explanation-2: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Detailed explanation-3: -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-4: -All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths.

Detailed explanation-5: -In plants, chlorophyll a and chlorophyll b are the main photosynthetic pigments. Chlorophyll molecules absorb blue and red wavelengths, as shown by the peaks in the absorption spectra above.
