Hint: Prokaryotic cells are primitive cells mainly found in the unicellular organisms, and they do not nucleus, instead they contain a fragment of DNA, and the organelles are not bounded by the membranes, where as the eukaryotic cells are found in all types of multicellular organisms such as plant and animal cells and they contains nucleus and membrane bound organelles.

Complete answer:
Prokaryotic cellsEukaryotic cells
This cells are always unicellularEukaryotic cells are present as either unicellular or multicellular.
The size of cell is generally range from 0.2 micrometers to 2.0 micrometers in diameterEukaryotic cells range from 10 to 100 micrometers in diameter.
In prokaryotic cells, the cell wall is present and it is very complex in nature.Eukaryotic cells have cell walls very rarely, if present they have simple chemical nature.
In this cells true nucleus absent, instead nucleotide is presentTrue nucleus is present.
DNA is arranged in circular shapeDNA is linear in shape
In prokaryotic cells, cytoplasm is present, but it is lacking in most cell organelles.In eukaryotic cells, it consists of both cytoplasm and organelles, both are present.
Mitochondria is absentMitochondria is present and it is a powerhouse of cells.
Ribosomes are present, and they are small in size and shape is sphericalRibosomes are present but they are comparatively large and linear in shape.
Endoplasmic reticulum and lysosomes and centromere’s all are absent Endoplasmic reticulum and lysosomes and centromere’s all are present.
Plasmids are commonly found in prokaryotes.Plasmids are very rarely found in eukaryotes
Cell division occur through binary fission Cell division occur through mitosis
Flagella is small in sizeIf flagella are large in size.
In this cells only asexual reproduction occurs.Both sexual and asexual reproduction occurs.
Bacteria and Archaea are examples.Plant and animal cells are examples.

Note: So prokaryotes are primitive cells compared to eukaryotes and in prokaryotes both transcription and translation occurred as couple, which means that translation begins during the time of synthesis of mRNA, while in eukaryotic cells, mRNA produce in nucleus and enters the cytoplasm where translation begins freshly.
