What are the 3 domains of life and what are the major differences?
All of life can be divided into three domains, based on the type of cell of the organism: Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.

What is not a domain of life?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. All life that has a cell nucleus and eukaryotic membrane-bound organelles is included in Eukarya. Non-cellular life is not included in this system.
What are the six kingdoms of living organisms?
The six kingdoms are Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia. Until the 20th century, most biologists considered all living things to be classifiable as either a plant or an animal.
What are the three domains into which organisms are classified?
Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), the cell’s membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.
What are the three domains and the kingdoms of living things?
Organisms are classified into three Domains and into one of six Kingdoms of life. These Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia . Organisms are placed into these categories based on similarities or common characteristics.
What are the three recognized domains of life?
eukarya have organelle like mitochondria and chloroplasts all within a cell membrane.
What domain contains the oldest living organisms on Earth?
Archaea are the oldest of the 3 domains of life. They make up a group of the first organisms to appear on Earth. We know this because they are used to extreme environments like those during the early Earth.
