Brown algae
brown algae, (class Phaeophyceae), class of about 1,500 Ectocarpus) to complex giant Laminaria, Macrocystis, Nerocystis). Other brown algae can be found attached to rocky coasts in Fucus, Ascophyllum) or floating freely ( Sargassum). Freshwater species are rare. Brown algae multiply by asexual and sexual reproduction; both the motile zoospores and gametes have two unequal

Correct option(c) fucoxanthin Explanation: ln additionto chlorophyll-a, brown algae posses. special carotenoids and fucoxanthin. It is due to the fucoxanthin (brown pigment) that these algae appear brown. Phycocyanin and phycoerythrin are phycobilins which are found in red algae (phycocyanin-r, phycoerythrin-r) and blue, green algae (phycocyanin-cphycoerythrin-c).

Solution: Brown algae are the members of the class phaeophyceae. Their chromatopores are ellipsoidal or discoid. They contain chlorophyll a, chi c, (i- and c- carotenes and xanthophyll pigments (e.g., lutein, flavoxanthin, violaxanthin). They also contain large amount of a brown pigment - fucoxanthin which masks the green colour of chlorophyll pigment. This gives characteristic brown colour to these plants, hence the name brown algae. The non-motile resting spores of Chlamydomonas contain a red pigment called hematochrome. phycocyanin and phycoerythrin are water soluble pigments found in red and blue-green algae.
