Eukaryotic Cell vs. Prokaryotic Cell. The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles.Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. Cell division is part of the life cycle of virtually all cells. 2  Cell division is the process in which one cell divides to form two new cells. 3  Most prokaryotic cells divide by the process of binary fission. 4  In eukaryotes, cell division occurs in two major steps: mitosis and cytokinesis.
