Morphology Red colour results from the dominance of the pigments phycoerythrin and phycocyanin; this masks the other pigments, chlorophyll a (no chlorophyll b), beta-caratene and a number of unique xanthophylls. [details]
Reproduction vegetative reproduction is rare; asexual reproduction is effected by the formation of various kinds of spores; Sexual reproduction is unique in this group due to their passive, non flagellated sperm cells (spermatia) [details]
