A graph plotting the absorption of light of different wavelengths by a pigment is called:
Correct answer: A. Absorption spectrum
- A. Absorption spectrum
- B. Spectrophotometer
- C. Carotenoids
- D. Xanthophylls
Explanation
The correct answer is absorption spectrum because it is a graph that shows how much light of different wavelengths is absorbed by a pigment. This graph is crucial in understanding which wavelengths of light are most effectively used by a pigment in processes like photosynthesis.The spectrophotometer is incorrect because it refers to an instrument, not a graph. Carotenoids and xanthophylls are specific types of pigments, not graphs or plots, and are therefore incorrect in this context.
