What groups of living organisms have a prokaryotic cell type?
1 Answer
Explanation:
Prokaryotes are single-celled organisms that lack a nucleus or any other membrane-bound organelles in their cells.
They are among the most abundant groups of organisms on earth, playing a crucial role in the Carbon Cycle and the Nitrogen Cycle.
Here's an image of the role of these microbes in recycling nutrients through the food chains

Archaea were initially classified as bacteria because they are generally similar in size and shape, but it has since been found that the Archaea have characteristics that are not shared by bacteria.
Archaea are particularly numerous in the oceans, but they also live in vast numbers in humans and other animals -- found on the skin, in the intestines, and in the mouth.
