BIO 161 Lab Quiz 1 Questions And Answers With
Complete Solutions 100% Correct | New Update
2025
what are the main and accessory pigments in plants, and what are these pigments
responsible for? - ANSWERS pigments: chlorophyll a, chlorophyll b, carotenes,
xanthophylls
pigments absorb light energy and convert this to chemical energy. accessory
pigments (carotene and xanthophyll) make photosynthesis more efficient by
absorbing light and transferring the energy to chlorophyll
what is the method used to separate pigments called? how can you quantify this?
- ANSWERS paper chromatography
retardation factor = distance pigment traveled/distance solvent traveled
used to quantify the movements of pigments along paper
what does a greater Rf mean? - ANSWERS greater Rf means greater distance
traveled, and thus greater solubility of the pigment
carotene - ANSWERS yellow, fast moving
xanthophyll - ANSWERS yellow, slow moving
