Question

what is the basis of classification of algae?

Answer 1

The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Early morphological research using electron microscopesdemonstrated differences in features, such as the flagellar apparatus, cell division process, and organelle structure and function, that have been important in the classification of algae. 

Answer 2

Answer:

Algae were classified into three main classes- Chlorophyceae, Phaeophyceae and Rodophyceae on the basis of pigmentation and types of stored food.
