Prokaryote - Wikipedia Prokaryotic cells are usually much smaller than eukaryotic cells This causes prokaryotes to have a larger surface-area-to-volume ratio, giving them a higher metabolic rate, a higher growth rate, and as a consequence, a shorter generation time than eukaryotes
Prokaryotic Cell Diagram and Facts A prokaryotic cell is a type of cell that lacks a defined nucleus and other membrane-bound organelles These cells are structurally simpler and smaller than their eukaryotic counterparts, the cells that make up fungi, plants, and animals

From prokaryotes to eukaryotes - Understanding Evolution How did a humble bacterium make this evolutionary leap from a simple prokaryotic cell to a more complex eukaryotic cell? The answer seems to be symbiosis — in other words, teamwork Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union
