Difference between Prokaryotic and Eukaryotic Cells

All living organisms are made up of cells. And based on the kind of cells they are made up of, they are divided into two groups: ‘prokaryotes’ and ‘eukaryotes’. Organisms whose cells lack a nuclear membrane are called Prokaryotes (Pro = primitive and Karyon = Nucleus). Examples of prokaryotes are bacteria and blue-green algae. The organisms with cells having well defined nucleus are called Eukaryotes. They are further divided into Plant Cell and Animal Cell. Prokaryotic cells divide by the method of binary fission and budding. Binary fission is the process of division in which cell divide and give rise to two daughter cells. Budding on the other hand is the process in which new organism develop from an outgrowth and bud.
