We can differentiate between two algae type that contain similar pigments by paper chromatography.

Rhodophyta and Phaeophyta

  • Rhodophyta are red algae and are the oldest eukaryotic algae. In red color algae, phycobiliprotein is present as pigment.
  • They are found abundantly in marine areas.
  • Phaeophyta are brown algae in which the chlorophyll is covered with a pigment called fucoxanthin.

Thus, by chromatography we can find out which pigment is present in the species and easily find out the species of the algae.
