Match the following:

$\begin{array}{cc}\text{Pigment}& \text{Colour}\\ a.\text{Chlorophyll a}& \left(i\right)\text{yellowish orange}\\ b.\text{Chlorophyll b}& \left(ii\right)\text{yellowish green}\\ c.\text{Carotene}& \left(iii\right)\text{yellow}\\ d.\text{Xanthophyll}& \left(iv\right)\text{bluish green}\end{array}$

The correct option is A

a - (iv), b - (ii), c - (i), d - (iii)

Chloroplast is an organelle with a double layered membrane. Pigments that can absorb sunlight are seen in the grana. Pigments like chlorophyll a, chlorophyll b, carotene and xanthophyll are seen in the grana. Chlorophyll a is bluish green, chlorophyll b is yellowish green, carotene is yellowish orange and xanthophyll is yellow in colour. All these pigments can absorb light. However only chlorophyll a can participate directly in photosynthesis. All other pigments absorb light and transfer it to chlorophyll a. Hence, they are called accessory pigments.
