Why did some molecules move up the paper really far while others remained close to the bottom of the paper??
CHLOROPHYLL B= Large molecule with two polar side groups. Will move the slowest. This is army green in color.
CHLOROPHYLL A= Also a large polar molecule with one polar side group. This will move the second slowest. This is a blue/green color.
XANTHOPHYLL= It’s yellow
BETA CAROTENE= Small molecule with no polar side groups. This is able to move up the paper the fastest.
It’s orange.
These chromatograms show chlorophyll b at the bottom,
followed by chlorophyll a,
xanthophylls, and carotenes.
Carotenes
Xanthophylls
Chlorophyll a
Chlorophyll b
These represent the pigments that are found in the spinach leaves.
What function do these pigments serve in plants???
Why does spinach have more than just one pigment?
Would a plant lacking pigment (white) be able to survive? WHY?
Below is the absorption spectrum for the spinach. Discuss with your partner the most useful/absorbed part of the visible
light spectrum and the least useful/absorbed part of the spectrum.
Plants need to be able to absorb light for the process of photosynthesis. The pigments in the plant are like buckets used to capture/collect this solar energy.
Based on the graph, what colors are best absorbed by this plant:
0%
7%
79%
14% 1. Green and orange
2. Red and violets
3. Violet and green
4. Green and reds

Look at the two graphs below. One shows the absorption spectrum for the spinach leaves. The other shows the rate of photosynthesis. Do you see a relationship between the two graphs??
