Document Summary
Prokaryotic cells are the structurally simpler of the two types of cells. Prokaryotic organisms include bacteria , both archaea and. Some of the earliest prokaryotic cells lived in dense mats similar to those that resemble stepping stones while others lived as free- floating, individual cells. Deinococcus radiodurans, which can survive 3 million rads of radiation (3,000 times the dose fatal to humans: other prokaryotes live in environments that are too cold or hot or salty for most other organisms, and some have surface. Their ability to live in a broad range of habitats helps explain why prokaryotes are the most abundant organisms on earth. Conditions on early earth made the origin of life possible. Observations and experiments in chemistry, geology, and physics have lead scientists to propose a scenario which explains the conditions of early earth that lead to origin of life.
