They are classified into four kingdoms. These do not have cell nuclei or other organelles.

Archaea domain archaea any of a group of single celled prokaryotic organisms that is organisms whose cells lack a defined nucleus that have distinct molecular characteristics separating them from bacteria the other more prominent group of prokaryotes as well as from eukaryotes organisms including plants and animals whose cells contain a defined nucleus.

Are archaea prokaryotic or eukaryotic. Their cells are smaller than eukaryotic cells. Archaea ɑːrˈkiːə listen or ɑːrˈkeɪə ar kee ə or ar kay ə singular archaeon constitute a domain of single celled organisms. These organisms are made of prokaryotic cells the smallest simplest and most ancient.

Most prokaryotes are unicellular and are either archaea or bacteria. Learn vocabulary terms and more with flashcards games and other study tools. Protists plants fungi and animals.

Archaea were initially classified as bacteria receiving the name archaebacteria in the archaebacteria kingdom. This in turn means that humans have evolved indirectly from archaea. Archaea and eukaryotes have some similar genetic processes so it is thought that archaea are evolutionary closer to eukaryotes.

The primarily single celled organisms found in the bacteria and archaea domains are known as prokaryotes. Eukaryotes are organisms that have membrane bound organelles. No plants are not prokaryotic.

Start studying prokaryotic eukaryotic archaea. Eukaryotes include larger more complex organisms such as plants and animals. All other life including plants is eukaryotic meaning that each cell contains a nucleus and other organelles.

The only prokaryotic organisms are bacteria and archaea which are the most primitive forms of life. Prokaryotes are single celled organisms that lack membrane bound organelles nucleus mitochondria etc. Archaea are ancient prokaryotes and humans are eukaryotes.

These microorganisms are prokaryotes and have no cell nucleus. Only eukaryotes have membrane bound organelles and a nucleus.
