Difference between Prokaryotic and Eukaryotic Cells

WebBoth bacteria and archaea are generally small compared to typical eukaryotes. For example, most bacteria tend to be on the order of 0.2 to 1.0 µm (micrometers) in diameter and 1-10 µm in length. However, there are exceptions. Epulopiscium fishelsoni is a bacillus-shaped bacterium that is typically 80 µm in diameter and 200-600 µm long. WebProkaryotes and eukaryotes are similar in some fundamental ways, reflecting their shared evolutionary ancestry.

Endosymbiotic Theory: How Eukaryotic Cells Evolve

WebPrevailing theory holds that eukaryotes came to be when a bacterium was swallowed by an archaeon. The engulfed bacterium, the theory holds, gave rise to mitochondria, whereas internalized pieces of the outer cell membrane of the archaeon formed the cell’s other internal compartments, including the nucleus and endomembrane system.
