Prokaryote electron micrograph
WebProkaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryote = "before carrier bag" i.e. without a nucleus Eukaryote = "good carrier bag" i.e. with a nucleus The close detail of a cell, with all organelles visible, that can be seen by using an electron microscope is refered to as the ultra-structure. WebThe two prokaryote domains, Bacteria and Archaea, split from each other early in the evolution of life. Bacteria are very diverse, ranging from disease-causing pathogens to …
