Detailed explanation-2: -Given below are some other catogories; Some general biology textbook authors place the microscopic, unicellular green algae (Division Chlorophyta) in the Kingdom Protista, and place the larger, multicellular (macroscopic) green algae (Division Chlorophyta) in the Kingdom Plantae.

Detailed explanation-3: -Kingdom protista includes unicellular eukaryotic organisms. Plant-like protists include diatoms, animal-like protists include protozoans like amoeba, euglena, paramecium, etc., while fungi like protists include slime molds.

Detailed explanation-4: -Algae are classified under the Kingdom Protista because they are eukaryotic, unicellular organisms with the Kingdom Protista trait. All single-celled eukaryotes are classified as Protista.

Detailed explanation-5: -Both Monera and Protista are kingdoms that are acknowledged during the classification of living organisms on earth. In simple words, Monera comprises archaebacteria, eubacteria and cyanobacteria, whereas Protista includes algae, protozoans and moulds.
