Description: Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a inpolar solvents because of its carbonyl group. Its color is yellow, and it primarily absorbs blue light. 

In land plants, the light harvesting antennae around photosystem II contain the majority of chlorophyll b. Hence, in shade adapted chloroplasts, which have an increased ratio of Photosystem II to Photosystem I, there is a lower ratio of chlorophyll a to chlorophyll b (Kitajima and Hogan 2003). This is adaptive as increasing chlorophyll b increases the range of wavelengths absorbed by the shade chloroplasts.
