Eukaryotes all have a distinct sort of cell.

The Tree of Life has an intricate network of branches that represents how a family grows and expands throughout many generations. It also symbolizes fertility as it always finds a way to keep growing, through seeds or new saplings, and is lush and green, which signifies its vitality.
What domain of life are viruses?
In their phylogenetic analysis of the RNAP2 sequences including 80 sequences, giant virus genes appeared at the base of the eukaryotic branch so that Boyer et al. [28] concluded that giant viruses constitute a fourth domain of life, sister to the eukaryotes.
Are Archaea older than Bacteria?
And it is no longer believed that Archaea are any older than Bacteria, as their name and the New York Times headline might imply. Now, probably all textbooks show Life as comprising the domains Bacteria, Archaea and Eukarya, with the last two the more closely related.

domain Eukarya
Humans belong to the domain Eukarya. The three domains are Eukarya, Archaea, and Bacteria.
What are the three domains of life give example?
The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
