Document Summary
All organisms are comprised of 1 or more cells. The cell is the basic organizational unit of life. Heredity is essential to the definition of life. Prokaryotic have no nuclei, they are primarily single celled (mostly), sometimes they live together in a community/colony. Eukaryotic cells have nuclei, they can be single celled or multi cellular, they tend to be much more complex than prokaryotes and are generally larger in size wth much larger genomes. Prokaryotes have 500-600 genes in a prokaryote, 22k in eukaryote. The ribosomes are free-floating, they aren"t attached to an internal membrane system. Propkaryotes have a nucleoid, prokaryote has no membrane-bound organelles. Volume of a euk cell is 1000x bigger than a pro cell. It has a membrane bound nucleus, it has a nucleolus, it has a cytoskeleton, and because the euk cel is so large, it needs a framework to move particles from one location to another.
