Compare and contrast prokaryotic and eukaryotic cells

Prokaryotes are usually smaller than eukaryotes. They also don’t have a nucleus so DNA is in the cytoplasm. They also have no organelle membranes where as eukaryotes do. Domains of prokaryotes include Bacteria and Archaea, and all eukaryotes are in the domain Eukarya. Both can be free living, but only eukaryotes can be multicellular. Prokaryotes first appeared on earth about 3.5 billions then eukaryotes appeared about a billion years later. Etc

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
