Archaebacteria are prokaryotic, unicellular, and reproduce asexually. They mostly like in environments without oxygen as oxygen is poisonous to them. Also, their cell wall doesn't have peptidoglycan, unlike those of eubacteria
Archaebacteria are described as being obligate anaerobes; that is, they can only live in areas without oxygen. Their oxygen-free environments, and the observations that habitats of Archaebacteria can frequently be harsh (so harsh that bacteria and eukaryotic organisms such as humans cannot survive), supports the view that Archaebacteria were ones of the first life forms to evolve on Earth.
Archaebacteria are microscopic organisms with diameters ranging from 0.0002-0.0004 in (0.5-1.0 micrometer). The volume of their cells is only around one-thousandth that of a typical eukaryotic cell. They come in a variety of shapes, which can be characterized into three common forms. Spherical cells are called cocci, rod shaped cells are called bacilli, and spiral cells can either be vibrio (a short helix), spirillum (a long helix), or spirochete (a long, flexible helix). Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts. The cells contain a thick cytoplasm that contains all of the molecules and compounds of metabolism and nutrition. Archaebacteria have a cell wall that contains no peptidoglycan. This rigid cell wall supports the cell, allowing an archaebacterium to maintain its shape, and protecting the cell from bursting when in a hypotonic environment. Because these organisms have no nucleus, the genetic material floats freely in the cytoplasm. The DNA consists of a single circular molecule. This molecule is tightly wound and compact, and if stretched out would be more than 1,000 times longer than the actual cell. Little or no protein is associated with the DNA. Plasmids may be present in the archaebacterial cell. These are small, circular pieces of DNA that can duplicate independent of the larger, genomic DNA circle. Plasmids often code for particular enzymes or for antibiotic resistance.
1. They are prokaryotic
2. They are unicellular
3. They reproduce asexually
4. They are autotrophs
Archaebacteria are unicellular prokaryotes that are the oldest living organisms on Earth. Some characteristics include survival in oxygen-free environments, being extremophiles and reproduction is asexual.
its carbon atoms have no double bonds between them.

I believe you are referring to the organism's Phenotype,it's physical characteristics.
Thi characteristic is the lack of double or triple bonds.
no but they do have distinguishing characteristics
Distinguishing characteristics are those characteristics that distinguish you or an object from others of its kind. Many products have features that are distinguishing characteristics.
After the discovery of archaebacteria, it was decided that archaebacteria and eubacteria have too many different characteristics that they need their own domains.

The distinguishing characteristic of homosexuality is a sexual attraction for individuals of the same gender. There is no other characteristic.

Objective and Subjective.
Scientists study physical, chemical, reproductive, and DNA characteristics of a subject species, and compare these results with the results from other archaebacteria.
