Filamentous algae are usually considered as ‘macrophytes’ since they often form floating masses that can be easily harvested, although many consist of microscopic, individual filaments of algal cells. Alga is the singular of algae with a changing size from microscopic unicellular micro-algae (Chlorella and Diatoms) to large massive kelps that are usually a length extending in meters (200 feet) and then there's brown alga. criteria such as structural characteristics, membrane composition, pigments color, and energy-storing molecules. 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. Haplontic life cycle, diplontic life cycle and triphasic life cycles are characteristic of different groups. It is the largest class of algae; They are commonly known as green Algae.
