What is studied to understand the ability of chlorophyll a to absorb light?

Step-by-step solution

A chromatographic separation of the leaf pigments shows that the colour that we see in leaves is not due to a single pigment but due to four pigments: Chlorophyll a (bright or blue green in the chromatogram), chlorophyll b (yellow green), xanthophylls (yellow) and carotenoids (yellow to yellow-orange). Let us now see what roles various pigments play in photosynthesis. Pigments are substances that have an ability to absorb light, at specific wavelengths. Can you guess which is the most abundant plant pigment in the
