A Prokaryote is a unicellular organism that lacks a membrane bound nucleus ( karyons ), a mitocondria, or anyof the membrane bounded organelles. In the prokaryote, and all the interacellular water soluble components ( protiens, DNA, and metabolites ) are located together in the cytoplasam enclosed by the cell membrane, rather than in seperate cellular components. Bacteria, however, they do process protien based bacterial microcomparments which are thought to be the act of primitive the organelles enclosed in a protien shell. Some prokaryote, such as the cyanobacteria may form large colonies. others such as myxobacteria, have a milticellular stage in their life cycles. Prokaryotes have a prokaryotic cytoskeleton albeit more primitive than that of the eukarytes. Besides homologes of actin and tubulin, the helically arranged building block of the flagellum, flagellin, is one of the most significant cytoskeleton protiens of bacteria, as it provides structural backgrounds of chemotaxis, the basic cell physological response of bacteria. At least some of the prokaryotes also contain intracellular structures that can be seen as primitive organelles. membranous organelles ( or intracellular membranes ) are known as in some groups of prokaryotes, such as the vacuoles or the membrane systen are devoted to special metabolic properties, such as photosynthesis or chemolithotrophy.
Flagella- Is a lash like appendage that protrudesfrom the cell body of certain eukaryotic cells.
