Some wavelengths _ by chlorophyll a are _ by chlorophyll b.
Correct answer: D. Absorbed, Reflected
- A. Absorbed, Absorbed
- B. Not absorbed, Weakly absorbed
- C. Not absorbed, Not absorbed
- D. Absorbed, Reflected
Explanation
Option D is correct. Chlorophyll a and chlorophyll b are both crucial for photosynthesis, and they have complementary absorption spectra. Chlorophyll a absorbs light primarily in the blue-green region, while chlorophyll b absorbs more in the red region. This means certain wavelengths absorbed by chlorophyll a are reflected by chlorophyll b, allowing plants to efficiently utilize a wider range of light. The other options are incorrect because they do not accurately describe the unique absorption and reflection properties of chlorophyll pigments.
