WebMay 21, 2024 · Only eukaryotes have membrane-bound organelles and a nucleus. Prokaryotes divide via using binary fission, while eukaryotic cells divide via mitosis. Eukaryotes reproduce sexually through meiosis, which allows for genetic variance. Prokaryotic cells reproduce asexually, copying themselves. WebAug 18, 2024 · A prokaryotic cell lacks a nucleus, but it does have the ribosomes, DNA, and cytoskeleton that eukaryotes do. Prokaryotes also do not have mitochondria or chloroplasts. Because of this lack of cellular organelles, they are considered prokaryotes. Despite this, prokaryotes can produce proteins.
