In lab you isolated pigments from leaves and compared their color under black light to that of an entire leaf. What did you observe? Explain any differences between the appearance of the two.
That the pigments that were MORE polar migrated a shorter distance on the paper and the LESS polar pigments traveled a greater distance. It also showed the different types of pigments present.
