School of Science and Technology, Online Counseling Resource… Appendages Bacteria can have two types of appendages: pili & flagella. A bacterium may have one, both or neither of these. The presence or absence of appendages depends on the species & the conditions under which it is cultivated. Bacterial flagella is responsible for its mobility. Some eukaryotes have flagella on their outer surface. Flagella serve the same function of motility but their structure & movement are completely different. Eukaryotic flagella are µm long. They are more complex than prokaryotic flagella & do not turn. They are membrane bound having 9+2 microtubules arrangement.
School of Science and Technology, Online Counseling Resource… What We Learn…………. Prokaryotes include single celled bacteria 1 micrometer in diameter. Eukaryotes include plants, animals & fungi & 10 times larger than prokaryotes. Prokaryotes have no different organelles as that of eukaryotes. Nuclear envelope is absent in prokaryotes. Prokaryotic genome is a single circular DNA while eukaryotic genome is made from chromosomes. Cell wall & cell membrane generally present in prokaryotes & in some eukaryotes. Cell division is different in both classes.
