Red algae | Brown algae |
Red algae possess chlorophyll a, d and phycoerythrin | Brown algae consist of chlorophyll a, c and fucoxanthin |
They contain floridean starch as reserve food material | Brown algae contain laminarin and mannitol as reserve food material |
Cell walls are composed of cellulose, pectin and phycocolloids | The cell wall is composed of cellulose and algin |
Red algae due to the presence of red pigment phycoerythrin, are grouped under Rhodophyceae | Brown algae due to the presence of fucoxanthin a brown pigment is grouped under Phaeophyceae |
