What are the 3 super groups of protozoans?
In this section, we will primarily be concerned with the supergroups Amoebozoa, Excavata, and Chromalveolata; these supergroups include many protozoans of clinical significance.

What supergroup does Stentor belong to?
Stentors are more commonly classified amongst an infrakingdom called the Alveolata and a subkingdom called the SAR supergroup.
What supergroup are animals classified?
Along with different groups of protists, animals and fungi are placed into the supergroup unikonta and plants are found in archaeplastida. The remaining three groups consist entirely of protists and the vast majority are microorganisms.
Are dinoflagellates unicellular or multicellular?
Dinoflagellates are unicellular protists which exhibit a great diversity of form.
Why are protists divided into supergroups?
The goal of this classification scheme is to create clusters of species that all are derived from a common ancestor. At present, the monophyly of some of the supergroups are better supported by genetic data than others.
What are choanoflagellates?
The choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals. Choanoflagellates are collared flagellates having a funnel shaped collar of interconnected microvilli at the base of a flagellum.
Is there homology between choanoflagellates and stramenopiles?
Analysis of choanoflagellate SiTs shows that they are similar to the SiT-type silicon transporters of diatoms and other silica-forming stramenopiles. The SiT gene family shows little or no homology to any other genes, even to genes in non-siliceous choanoflagellates or stramenopiles.
Are choanoflagellates unicellular protists?
Choanoflagellates are small unicellular protists comprising both marine and freshwater species (Fig. 6.1A). According to current molecular phylogenies, choanoflagellates are the closest unicellular relative of metazoans (King et al., 2008 ).
