Pigment A is the least polar. The answer is E. Polar molecules carry charge- remember the example I gave with water molecules in lecture. The answer is B. Carbohydrates are energy molecules composed of simple sugar units. Oxygen is produced during photosynthesis. Chlorophyll is found within chloroplasts.
All chlorophylls absorb light in the green portion of the spectrum.
Accessory pigments allow a greater portion of the energy of the light spectrum to be utilized by the plant. The answer is D. Chlorophylls absorb in various wavelengths of the spectrum. The chromatograms above represent pigments from 5 different photosynthetic organisms. All the chromatograms share one specific pigment. Chromatograms D and E share two pigments.
