We find prokaryotes in Kingdom Monera.
R. H. Whittaker proposed the five-kingdom classification in the year 1969. The kingdom Monera comprises unicellular prokaryotic organisms.
- This group contains bacteria and cyanobacteria species.
- These are prokaryotic organisms that do not have well-developed cell organelles like the nucleus, mitochondria, and chloroplast.
- The other four kingdoms, Protista, Fungi, Plantae and Animalia, are composed of all the eukaryotic organisms.
A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. As a result, Prokaryotic are much smaller than the smallest eukaryotic cells. In general, a prokaryotic cell is smaller because it has less DNA to create the proteins needed to make an ultra-efficient membrane. In addition, prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do.
