Q. If you are asked to classify the various algae into distinct groups, which of the following characters you should choose?
A) nature of stored food materials in the cell
B) structural organization of thallus
C) chemical composition of the cell wall
D) types of pigments present in the cell
Explanation
[Solution from source] Algae are divided into Chlorophyceae, Phaeophyceae and Rhodophyceae chiefly by their major pigments (chlorophyll a and b, fucoxanthin, r-phycoerythrin), which give the green, brown and red colours. Stored food and cell wall also differ, but the primary basis of grouping is pigments. Answer (4).
