Chlorophyll b is:
Correct answer: A. Yellow - Green
- A. Yellow - Green
- B. Blue - Yellow
- C. Blue - Green
- D. None of these
Explanation
Option A is correct. Chlorophyll b appears yellow-green because it absorbs light primarily in the blue and yellow regions of the spectrum, reflecting green. This reflection of green light gives chlorophyll b its characteristic yellow-green appearance. Option B is incorrect because chlorophyll b does not appear blue-yellow; it reflects green light, not blue. Option C is incorrect because chlorophyll a, not b, absorbs blue-green light. Option D is incorrect because chlorophyll b is indeed yellow-green in appearance.
