Q. No.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
