What are the 5 supergroups that are currently used to classify eukaryotic organisms?
One current classification separates all eukaryotes into five supergroups: Excavata, Chromalveolata, Rhizaria, Archaeplastida and Unikonta. Along with different groups of protists, animals and fungi are placed into the supergroup unikonta and plants are found in archaeplastida.
How many supergroups does Eukarya have?
six supergroups
Currently, the domain Eukarya is divided into six supergroups. Within each supergroup are multiple kingdoms.
What are the four major clades supergroups of eukaryotes?
The largest categories of eukaryotes have been defined, and they are called the eukaryotic supergroups. There are four of them presently, and so the eukaryotes can be divided into four groups. Here’s an introduction to the archaeplastida, SAR, excavata, and unikonts aka Amorphea.
What are supergroups in biology?
The supergroups are believed to be monophyletic, meaning that all organisms within each supergroup are believed to have evolved from a single common ancestor, and thus all members are most closely related to each other than to organisms outside that group.
What are the 6 supergroups in domain Eukarya?
Nearly all of eukaryotic diversity has been classified into 6 suprakingdom-level groups (supergroups) based on molecular and morphological/cell-biological evidence; these are Opisthokonta, Amoebozoa, Archaeplastida, Rhizaria, Chromalveolata, and Excavata.
Which supergroup of eukaryotes includes amoebas?
Rhizaria supergroup
The Rhizaria supergroup includes many of the amoebas, most of which have threadlike or needle-like pseudopodia (ammonia tepida, a Rhizaria species, can be seen in Figure 13).
Which supergroup contains both Alveolates and Stramenopiles?
The SAR supergroup, also just SAR or Harosa, is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria. The name is an acronym derived from the first letters of each of these clades; it has been alternatively spelled “RAS”. The term “Harosa” (at the subkingdom level) has also been used.
Which supergroup of eukaryotes includes amoeba?
The Rhizaria supergroup
Rhizaria. The Rhizaria supergroup includes many of the amoebas, most of which have threadlike or needle-like pseudopodia (ammonia tepida, a Rhizaria species, can be seen in Figure 13).
How do protists Remember supergroups?
my mnemonic to remember Protist supergroups: “Excavating stars for ancient, plastic unicorns” Excavata, SAR Clade, Archaeplastids, Unikonta.
Which supergroup includes animals?
“Opisthokonta” includes animals, fungi, and their microbial relatives. This supergroup emerged from molecular gene trees [24] and is united by the presence of a single posterior flagellum in many constituent lineages [25].
Which group within the SAR supergroup have a hairy flagellum paired with a smooth flagellum?
Stramenopiles. A subgroup of chromalveolates, the stramenopiles, also referred to as heterokonts, includes photosynthetic marine algae and heterotrophic protists. The unifying feature of this group is the presence of a textured, or “hairy,” flagellum.
What supergroup is chlorophyta in?
Some members of the group form symbiotic relationships with protozoa, sponges, and cnidarians. Others form symbiotic relationships with fungi to form lichens, but the majority of species are free-living….
| Chlorophyta | |
|---|---|
| Chlorophytes (A–F, H–L and O) | |

What are the 5 eukaryotic supergroups?
Haptista. Haptista comprises the haptophyte algae (previously assigned to chromalveolates; Box 1) and centrohelids.
What are the four main groups of eukaryotes?
Animalia. Organisms in the animalia kingdom are multicellular and don’t have cell walls or photosynthetic pigments.
Which prokaryote is closer to the eukaryotes?
– It is a thin phospholipid bilayer and composed of two layers of lipid molecules which separate the cell components from the outside. – The plasma membrane is about 6 to 8 nanometers thick. – It is located beneath the cell wall. – It regulates the flow of substances in and out of the cell.
How many Oric do prokaryotes vs eukaryotes have?
Prokaryotes typically have one chromosome (there is a bacterium that has two chromosomes), and eukaryotes always have more than one. Prokaryotes have flagella and pili that help them with their motility. Flagella are taller and have more of a “tail” shape while pili are shorter and have more of a “hair” shape.
