Which wave lengths are mainly absorbed by chlorophyll?
Correct answer: A. Violet blue and red
- A. Violet blue and red
- B. Green and blue
- C. Violet and orange
- D. Red and indigo
Explanation
Chlorophyll primarily absorbs light in the blue and red regions of the electromagnetic spectrum. The violet-blue and red wavelengths are most efficiently absorbed by chlorophyll, while green wavelengths are less effectively absorbed and are, instead, reflected, which is why chlorophyll-containing plants appear green to our eyes.
