Question

why does chlorophyll b appear yellow - green?
a. it is the color of light it uses most efficiently.
b. it reflects light in those wavelengths and absorbs violet and red.
c. it absorbs those wavelengths and reflects yellow and orange.
why did the different photosynthetic pigments migrate to different points on the chromatography paper?
a. the molecular motion is based only on the molecular weights of the pigments.
b. the pigments differ in their solubility in the solvent and affinity for the paper.
c. the molecular motion of some pigments is greater than others.
d. some pigments are more temperature sensitive than others.

Explanation:

Chlorophyll b appears yellow - green because it reflects light in those wavelengths and absorbs violet and red. In chromatography, different photosynthetic pigments migrate to different points due to differences in their solubility in the solvent and affinity for the paper.

Answer:

1. B. It reflects light in those wavelengths and absorbs violet and red.
2. B. The pigments differ in their solubility in the solvent and affinity for the paper.
