WebWhile there are several characteristics that are common to all cells, such as the presence of a cell membrane, cytoplasm, DNA and ribosomes, not all cells are the same. Prokaryotic cells lack a nucleus and membrane-bound organelles. Eukaryotic cells are compartmentalized by membrane-bound organelles with specialized functions. WebOrganisms with nuclei are placed in a third domain, Eukaryota. [5] In biological evolution, prokaryotes are deemed to have arisen before eukaryotes. Besides the absence of a nucleus, prokaryotes also lack mitochondria, or most of the other membrane-bound organelles that characterize the eukaryotic cell.
