A student observed an alga with chlorophyll 'a', 'd' and phycoerythrin; it should belong to :
A
Phaeophyta
B
Rhodophyta
C
Chlorophyta
D
Bacillariophyta
Detailed Solution
Red algae (Rhodophyta) contain chlorophyll a and d, and the red pigment r-phycoerythrin, which gives them their red colour and lets them absorb blue-green light in deep water.
Brown algae have chlorophyll a, c and fucoxanthin; green algae have chlorophyll a and b; diatoms have chlorophyll a, c and fucoxanthin.
So the alga belongs to Rhodophyta.
