In addition to the absence of a nucleus their genomes are less. Prokaryotic cells bacteria lack a nuclear envelope.

During Margulis research on the origin of eukaryotic cells she studied data on prokaryotes eukaryotes and organelles finally proposing that similarities between prokaryotes and organelles combined with their appearance in the fossil record was best explained by something called endosymbiosis meaning to cooperate inside.

. Cytoplasm is composed mainly of water but also contains enzymes. Cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cellIt is clear in color and has a gel-like appearance. Cells are divided into two main classes initially defined by whether they contain a nucleus.

Prokaryotic cells are generally smaller and simpler than eukaryotic cells. Eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Ribosomes give the cytoplasm of bacteria a granular appearance in electron micrographsThough smaller than the ribosomes in eukaryotic cells these inclusions have a similar function in translating the genetic message in messenger RNA into the production of peptide sequences proteins.
