Non-cellular life, also known as acellular life, is life that exists without a cellular structure for at least part of its life cycle. Historically, most...

membrane-bound organelles are included in Eukarya and called eukaryotes. Non-cellular life, most notably the viruses, is not included in this system. Alternatives...
