These are spread across th… Algae - Algae - Classification of algae: 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. Certain environmental conditions in water bodies can intensify algae growth, causing algal blooms. AAU,Anand.
