Chlorophyll and Carotenoid Absorption Spectra Explained #2172903 (License: Personal Use)

The chart displays the relative light absorption of three key photosynthetic pigments-chlorophyll a (green curve), chlorophyll b (dark green), and carotenoids (orange)-across wavelengths from 400 to 700 nm. Chlorophyll a shows strong peaks near 430 nm and 662 nm, while chlorophyll b absorbs more in the blue-orange range (~453 nm and 642 nm); carotenoids complement by absorbing strongly in the blue-green region (~450-500 nm). These absorption profiles explain why plants appear green and how they maximize solar energy capture.
