Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.
