Document Summary

Eukaryotes and prokaryotes differ in internal organization: all cells have a plasma membrane and contain genetic information. Eukaryotes have cholesterol in their cell membranes and synthesize sterols. Prokaryotic cells lack a nucleus and extensive internal compartmentalization. Instead of a physically separated nucleus, prokaryotic cells have nucleoids: a discrete region of the cell interior in which dna is concentrated in: bacteria often contain plasmids: additional small circular molecules of. Pili: threadlike structures that facilitate plasmid transferal between bacteria cells. Prokaryotes are 1-2 microns in diameter or smaller. Prokaryotes have relatively high ratio of surface area to volume. Prokaryotes lack the extensive internal organization characteristic of eukaryotes. Eukaryotic cells have a nucleus and specialized internal structures. The nucleus houses the genome and is the site of rna synthesis: nucleus: the innermost organelle of the endomembrane system, stores dna, nuclear envelope: de nes the boundary of the nucleus, consists of inner and outer membranes.
