which group of protists to euglena belong to
Euglena The venerable Euglena viridis was found to be genetically closer to Khawkinea quartana than to the other species of Euglena studied.[32] Recognizing the polyphyletic nature of the genus Euglena, Marin et al. (2003) have revised it to include certain members traditionally placed in Astasia and Khawkinea.[16]
Protozoa Historically, the Protozoa were classified as "unicellular animals", as distinct from the Protophyta, single-celled photosynthetic organisms (algae) which were considered primitive plants. Both groups were commonly given the rank of phylum, under the kingdom Protista.[45] In older systems of classification, the phylum Protozoa was commonly divided into several sub-groups, reflecting the means of locomotion:[46] Classification schemes differed, but throughout much of the 20th century the major groups of Protozoa included:
Animal Animals are eukaryotic, multicellular organisms that form the biological kingdom Animalia. With few exceptions, animals are motile (able to move), heterotrophic (consume organic material), reproduce sexually, and their embryonic development includes a blastula stage. The body plan of the animal derives from this blastula, differentiating specialized tissues and organs as it develops; this plan eventually becomes fixed, although some undergo metamorphosis at some stage in their lives.
Fungus The 2007 classification of Kingdom Fungi is the result of a large-scale collaborative research effort involving dozens of mycologists and other scientists working on fungal taxonomy.[41] It recognizes seven phyla, two of which—the Ascomycota and the Basidiomycota—are contained within a branch representing subkingdom Dikarya, the most species rich and familiar group, including all the mushrooms, most food-spoilage molds, most plant pathogenic fungi, and the beer, wine, and bread yeasts. The accompanying cladogram depicts the major fungal taxa and their relationship to opisthokont and unikont organisms, based on the work of Philippe Silar,[125] "The Mycota: A Comprehensive Treatise on Fungi as Experimental Systems for Basic and Applied Research"[126] and Tedersoo et al. 2018.[127] The lengths of the branches are not proportional to evolutionary distances.
