prokaryotes and eukaryotes

they are primitive organisms

they do not have a nucleus

 they have single loop of DNA

they are bounded by a cell wall

they are unicellular organisms eg bacteria and cyanobacteria

they respire through mesosomes

have small ribosomes as compared to eukaryotic cells 

they are advanced living organism

they have a nucleus bounded by nucleus menbrane

they have DNA within chromosomes(DNA with many loops)

they have cell membrane (in animals) and  cell wall (in plants )

they are multicellular organisms eg humans

they respire through mitochondria

they have large ribosomes as compared to prokaryotic cells
