28 wrz 2021 · Perform Paper Chromatography on Leaves. The key steps are breaking open the cells in leaves and extracting the pigment molecule and then separating the pigment using the alcohol and paper. Finely chop 2-3 leaves or several small leaves. If available, use a blender to break open the plant cells.
Procedure: 1. Cut chromatography paper into a strip that will fit into the graduated cylinder. Cut one end of the chromatography paper into a point or tip. Make a light pencil line about 1.5 cm from the end of the paper you just cut. 2. Use the coin to extract plant pigments from the leaf.
There are four different pigment groups present in leaves of photosynthesizing plants. Studies indicate that only the chlorophyll IS involved in the actual absorption of light energy and later conversion to chemical energy of living cells. The other pigments also absorb light energy, but it
