Chl a, Chl d and phycoerythrin occur in
1. | Chlorophyceae | 2. | Bacillariophyceae |
3. | Cyanophyceae | 4. | Rhodophyceae |
A species of red algae has been discovered near Bahamas at a depth of more than 260 m. This unusual feat is possible because this alga:
1. | lacks pigmentation and functions heterotrophically as parasite on other plants |
2. | has significant amount of phycoerythrin in addition to chlorophyll a and d |
3. | unlike other red algae has flagellated gametes |
4. | it has large number of root like rhizoids enabling it to attach to a deep substratum |
Major pigments | Stored food | Cell wall | Flagella | |
1. | Chlorophyll a, d; phycoerythrin | Mannitol. Laminarin | Cellulose, pectin, polysulphate esters | 2-8, equal, apical |
2. | Chlorophyll a, d; phycoerythrin | Floridean starch | Cellulose, pectin, polysulphate esters | Absent |
3. | Chlorophyll a, c; Fucoxanthin | Mannitol. Laminarin | Cellulose and algin | 2, unequal, lateral |
4. | Chlorophyll a, b; | Starch | Cellulose | 2-8, equal, apical |
