Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Yellowish green
Concept:

Different types of chlorophyll have slight structural differences that shift their absorption spectra, resulting in different visible colors.

Solution:

  • Chlorophyll a appears blue-green.
  • Chlorophyll b appears yellow-green.
  • This difference allows plants to broaden the spectrum of light they can effectively absorb.


Why other options are incorrect:

  • Bluish-green is the characteristic color of chlorophyll a.
