Prokaryotes are all single-celled organisms, most of which you know of as bacteria. For example, the famous (or infamous) Escherichia coli bacterium is a prokaryote, as is the streptococcus bacterium responsible for strep throat. The Streptomyces soil bacteria, from which the antibiotic streptomycin is derived, is also a prokaryotic organism.
Prokaryotic cell lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. In prokaryotic cell, all the intracellular components such as , DNA, RNA, proteins and metabolites are located together in the cytoplasm rather than in separate cellular compartment.
Every living organism can be categorized as either a prokaryote or a eukaryote. There are many different examples of both types of organisms. Learn about prokaryotes and eukaryotes, and test your ...
Prokaryotic- bacteria Eukaryotic- protist, amoeba, etc. An example of a prokaryote would be bacteria or any single cellular organism and an example of a eukaryote would be any multicellular organism.
Eukaryotes represent a tiny minority of all living things. However, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.
The eukaryotic cells are identified by the presence of a distinct nucleus with the genetic material enclosed inside it. They also have differences in the process of protein synthesis, RNA structures, etc. See for more details the differences between prokaryotes and eukaryotes. Examples of eukaryotic cells include: 1.
The metabolism of prokaryotes is far more varied than that of eukaryotes, leading to many highly distinct prokaryotic types. For example, in addition to using photosynthesis or organic compounds for energy, as eukaryotes do, prokaryotes may obtain energy from inorganic compounds such as hydrogen sulfide.
Almost every organism you can see without a microscope -- and some microscopic organisms as well -- are examples of eukaryotes. Eukaryotes have many cellular characteristics that distinguish them from prokaryotes like bacteria. For example, all eukaryotes have complex organelles, including a cytoskeleton, a ...

Prokaryote Definition. Prokaryotes are unicellular organisms that consist of a single prokaryotic cell.Prokaryotic cells are simple cells that do not have a true nucleus or other cell organelles. Bacteria and Archaea are the two domains of life that are prokaryotes. Prokaryotes can be contrasted with eukaryotes, which have more complex eukaryotic cells with a nucleus and organelles.
