Exercise 21 - NCERT
The four major photosynthetic pigments have been separated by chromatography and identified. This process of separation is called monodimensional ascending chromatography since the solution and pigments move upwards in one direction only. Fig. 23.1Loading of pigment extract Fig. 23.2Experimental setup of the chromatography Fig. 23.3A chromatogram
