Vedclass · Answer

(A) In a typical green leaf,the photosynthetic pigments are present in specific proportions. Chlorophyll $a$ and chlorophyll $b$ are the primary pigments,while carotenoids (which include xanthophylls and carotenes) act as accessory pigments. The molar ratio of total chlorophyll to xanthophyll is generally observed to be $4:1$ in many plant species. This ratio is essential for the efficient absorption of light energy and the protection of the photosynthetic apparatus from photo-oxidation.

List-I(Pigments)	List-II(Colour in chromatogram)
1. Chlorophyll 'b'	p. Yellow orange
2. Carotenoids	q. Orange red
3. Chlorophyll 'a'	s. Blue green
4. Xanthophylls	r. Yellow
-	t. Yellow green

What is the molar ratio of chlorophyll to xanthophyll in a typical leaf (in $:1$)?
