A spectrophotometer measured the absorption of pure chlorophyll a and chlorophyll b across 400-700 nm.
What does the dip near 550 nm (green) indicate about chlorophyll a and b?
- A
Chlorophyll absorbs green most strongly, which drives the Calvin cycle
- B
Green wavelengths damage chlorophyll molecules
- C
Green light has the most energy for splitting water
- Dcheck_circle
Green light is reflected/transmitted, not efficiently absorbed for photosynthesis
Explanation
Chlorophylls absorb red and blue light most strongly and reflect/transmit green wavelengths, which is why leaves appear green.
