Prokaryotic and eukaryotic flagella <u>have different structures .</u>
<h3>What are Prokaryotic ?</h3>
Any organism without internal membranes is referred to as a prokaryote, usually written procaryote. One of the most well-known prokaryotic species is bacteria. Prokaryotes differ from eukaryotes by not having internal membranes.
Prokaryotic cells are those that lack membrane-bound organelles and have their genetic material floating freely inside of their cell wall.
All prokaryotic cells have a nucleoid area, ribosomes, which create proteins, DNA and RNA as their genetic material, and cytosol, which has a cytoskeleton and organizes cellular components. Prokaryotic creatures, on the other hand, are a tremendously diverse collection of living things and exist in a wide range of sizes and shapes.
