The following are the differences between prokaryotes and eukaryotes:

ProkaryotesEukaryotes
Prokaryotes are always unicellularEukaryotes are unicellular as well as multicellular
Cell size ranges from 0.2-2.0 µm in diameterCell Size ranges from 10-100 µm in diameter
Usually, a cell wall is present which is chemically complex in natureIf a cell wall is present it is chemically simple in nature
Double membraneous cell organelles such as the nucleus, mitochondria, endoplasmic reticulum, and single membraneous organelles such as lysomoses and centrosomes are absentDouble membraneous cell organelles such as the nucleus, mitochondria, endoplasmic reticulum, and single membraneous organelles such as lysosomes and centrosomes are present
Ribosomes are smaller in size and spherical in shapeRibosomes are comparatively larger in size and linear in shape
DNA arrangement circular   DNA arrangement linear
Plasmids  are present   Plasmids  are very rarely found in eukaryotes
Cell division is through  binary fission and reproduction is Asexual   Cell division is through mitosis and reproduction is Both asexual and sexual
