Prokaryotic structure

WebMay 4, 2024 · Prokaryotic microorganisms are classified within the domains Archaea and Bacteria. The structures inside a cell are analogous to the organs inside a human body, with unique structures suited to specific functions. Some of the structures found in prokaryotic cells are similar to those found in some eukaryotic cells; others are unique to prokaryotes. WebMay 21, 2024 · Most prokaryotes are unicellular and are either archaea or bacteria. Their cells are smaller than eukaryotic cells. Eukaryotes include larger, more complex organisms such as plants and animals. Only eukaryotes have membrane-bound organelles and a nucleus. Prokaryotes divide via using binary fission, while eukaryotic cells divide via mitosis.
