Why are algae classified as protists?
Protists are eukaryotes as they possess a nucleus and other membrane-bound organelles (structures that perform a specific job). At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.

- Ulothrix.
- Fucus.
- Porphyra.
- Spirogyra.
What is the five classification of algae?
A generally agreed classification of algae recognizes nine broad taxonomic groups, called Divisions. These are Chlorophycophyta, Xanthophycophyta, Bacillariophycophyta, Phaeophycophyta, Rhodophycophyta, Chrysophycophyta, Euglenophycophyta, Cryptophycophyta and Pyrrophycophyta.
What is the most specific level of classification?
Levels of Classification. The classification system commonly used today is based on the Linnean system and has eight levels of taxa; from the most general to the most specific, these are domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.
What is the scientific name of algae?
The algae are further grouped into various phyla and the suffix –phyta is used in the classification of algae: Euglenophyta (euglenids), Chrysophyta (diatoms), Pyrrophyta (dinoflagellates), Chlorophyta (green algae), Phaeophyta (brown algae), and Rhodophyta (red algae).
What is the basic unit of classification?
species
Answer: The basic unit for classifying is species. Species is a morphologically related group of creatures that can interbreed. A species is the fundamental unit of categorization and taxonomic order of an individual in biology and is also a component of biodiversity.
