Characteristics of Archaebacteria, Eubacteria, and Protista!

Question

what makes things fall into these categories and what are their differences?

Answer 1

Eubacteria

- Cell wall of peptidoglycan

- can live nearly anywhere

- Unicellular

-Prokaryotic

- Reproduce Asexually

Archaebacteria

- Cell wall without peptidoglycan

- Live in environments without oxygen

- Prokaryotic

- Unicellular

-Reproduce Asexually

Protista (Generally)

- Need Water

- Eukaryorytic

- Can be Oblgate Aerobes, Anaerobes or Facultative Anaerobes.

- Reproduce both aseuxally and sexually.

- Known as the 'junk' drawer of biology

- generally unicellular

Answer 2

Ahh I remember when It was Protista and Moneara my how times change.

Anyway they are all single cell lifeforms.

Currently, the term protist is used to refer to unicellular eukaryotes that either exist as independent cells, or if they occur in colonies, do not show differentiation into tissues

Archaea [ɑrˈkiə] (help·info) are a group of single-celled microorganisms. A single individual or species from this domain is called an archaeon (sometimes spelled "archeon"). Archaea, like bacteria, are prokaryotes and have no cell nucleus or any other organelles within their cells. In the past they were viewed as an unusual group of bacteria and named archaebacteria but since the Archaea have an independent evolutionary history and show many differences in their biochemistry from other forms of life, they are now classified as a separate domain in the three-domain system. In this system, introduced by Carl Woese, the three main branches of evolutionary descent are the Archaea, Eukaryota and Bacteria. Archaea are further divided into four phyla of which two, the Crenarchaeota and the Euryarchaeota, are most intensively studied. Classifying the Archaea is still difficult, since the vast majority of these organisms have never been studied in the laboratory and have only been detected by analysis of their nucleic acids in samples from the environment.

The Bacteria [bækˈtɪr.i.ə] (help·info) (singular: bacterium) are a group of unicellular microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria are ubiquitous in every habitat on Earth, growing in soil, acidic hot springs, radioactive waste,[1] seawater, and deep in the Earth's crust. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×1030) bacteria on Earth,[2] forming much of the world's biomass.[3] Bacteria are vital in recycling nutrients, and many important steps in nutrient cycles depend on bacteria, such as the fixation of nitrogen from the atmosphere. However, most of these bacteria have not been characterized, and only about half of the phyla of bacteria have species that can be cultured in the laboratory.[4] The study of bacteria is known as bacteriology, a branch of microbiology.
