Explanation:
Detailed explanation-1: -Plants absorb red and blue colors of light because these are the wavelengths of light that are most effective for photosynthesis. Specifically, red and blue light are absorbed by pigments called chlorophylls, which are located in the thylakoid membranes of plant cells.
Detailed explanation-2: -When a photon reaches the chlorophyll a in the reaction center, that chlorophyll can receive the energy because it absorbs photons of longer wavelengths than the other pigments.
Detailed explanation-3: -Chlorophyll still absorbs light, but uncoupled from the photosynthetic apparatus, the absorbed light energy has nowhere to go, and a large red glow is visible.
