The third domain is Eukaryota, whose members are called eukaryotes. Many eukaryotes are unicellular, and many are multicellular. Whether consisting of one cell or many, all Eukaryotic cells are complex, having a nucleus and other complex organelles.
Living things have evolved into three large clusters of closely related organisms, called domains: Archaea, Bacteria, and Eukaryota. Archaea and Bacteria are small, relatively simple cells surrounded by a membrane and a cell wall, with a circular strand of DNA containing their genes. They are called prokaryotes. Virtually all the life we see each day â including plants and animals â belongs to the third domain, Eukaryota. Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal power plants, called mitochondria. These tiny organelles in the cell not only produce chemical energy, but also hold the key to understanding the evolution of the eukaryotic cell.
