WebEukaryotes are organisms made of one or more eukaryotic cells. The earliest eukaryotes, like the first prokaryotes, were single-celled organisms. They arose about 1 billion years later than the earliest prokaryotes. Later, multicellular eukaryotes arose. Every type of multicellular organism that exists is made up of eukaryotic cells. WebBecause it posits that eukaryotes evolved from the mitochondrial endosymbiosis in a prokaryotic host, this theory directly accounts for the ubiquity of mitochondria among all eukaryotic lineages.
