Brown algae is characterized by the presence of
Options
A.phycocyanin
B.phycoerythrin
C.fucoxanthin
D.haematochrome
Solution
In addition to chlorophyll-a, brown algae posses special carotenoids and fucoxanthin. It is due to fucoxanthin (brown pigment) that these appear brown.
Phycocyanin and phycoerythrin are phycobilins which are found in red algae (phycocyanin-r, phycoerythrin-r) and blue- green algae (phycocyanin-c, phycoerythrin-c). Haematochrome is a red pigment which provides red appearance to a cell.
