What is the primary plant pigment responsible for absorbing light energy during photosynthesis, containing a porphyrin ring with a central magnesium atom?

💡 Solution & Explanation

Chlorophyll serves as the essential green pigment in plants containing a substituted porphyrin ring coordinated with a central magnesium ion, enabling the absorption of light energy during photosynthesis. Anthocyanins provide red or blue coloration in flowers and fruits, while carotenoids and xanthophylls act as accessory pigments. Photosynthesis primarily utilizes blue and red wavelengths of light captured by chlorophyll molecules.
