A student analyzes the absorption spectrum of a leaf extract. At which wavelengths will the primary photosynthetic pigment, chlorophyll a, show maximum peaks?
Q1. A student analyzes the absorption spectrum of a leaf extract. At which wavelengths will the primary photosynthetic pigment, chlorophyll a, show maximum peaks?
Answer: Blue-violet and red light
Explanation: Chlorophyll a absorbs mainly blue-violet and red light. Option C fails because green light is reflected, not absorbed, by most photosynthetic pigments.
