Prokaryotic and Eukaryotic Cell Body of lung organisms except virus has cellular organization and may contain one of manycells. The organisms with only one cell in their body are known as unicellular (bacteria, protozoa, etc.) and organims with many cells in their body are known as multi celular organisms (most plants and animals). Any cellular organization may contain only one type of cell from the following types: A - Prokoryptic cells B - Eukaryotic cells These terms were soggested by Hans Ris in the 1960's. Prokaryotic Cells The prokaryonic (Gs., pro: promitive or before and karyon. nucleus) are small, simple, and most primitive. They are probably fest to come untu existence perhaps 3,5 billion years ago, These cells occur in bacteria (I.e. Mycoplasma, Cyanobacteria, etc.). Prokaryone cell is a one envelope system organized in depth. It consists of central nuclear components surrounded by cytoplas mic ground substance, with whole enveloped by a plasma membrane. The cytoplasm of prokaryone cell lacks nuclear envelope and any other cyroplasmic membrane and well detined cytoplasmic organelles.
