In the beet leaf/petroleum ether acetone trial, the carotene pigment travelled the furthest with a displacement of 9.0 cm [up]. Chlorophyll a and b are two common types of chlorophyll found on the thylakoid membrane in several photosynthetic units. Both have a similar purpose: to trap light to ultimately convert it into energy.
Leaf Chromatography | Science project | Education.com
The orange colored band, made of the pigment called carotenoids. is the most soluble in alcohol, so it traveled the farthest. The yellow xanthophylls are the next most soluble, followed by the blue-green chlorophyll A. The least soluble pigment is the yellow green chlorophyll B. You may be wondering why plants have more than one pigment.
