prokaryotes:

Always unicellular

smaller than eukaryotes

no membrane bound organelles

Dna in their cytoplasm

divide by binary fission


Eukaryotes:

divide by mitosis

usually multicellular

larger than prokaryotes (100x)

have membrane bound organelles like mitochondria

dna in nucleus

Eukaryotic cells are the usual plant and animal cells that we think of. So animal cells - DNA in a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells- Rigid cell wall, permanent vacoule, chloroplasts along with Nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.

Then prokaryotic cells are single celled organisms such as bacteria. These are arranged slightly differently in the fact that they do not have a nucleus, instead the DNA is in freely moving strands or plasmids in the cytoplasm. They also do not have mitochondria or chloroplasts, but they do have a cytoplasm, cell membrane and cell wall.

Eukaryotic cells are way bigger, complex cells found in multicellular organisms. The genetic material in eukaryotic cells is stored in the Nucleus in contrast to prokaryotic stored in the cytoplasm

The major difference is the Prokaryotes does not have a defined Nucleus, they lack nuclear membrane, therefore their genetic material lies in cytoplasm generally prokaryotes are primitive organisms. Where as Eukaryotes have a well defined Nucleus with the Nuclear Membrane. The term "Eu" stands for "true" and "Karyote" means nucleus, there by Eukaryotes are organisms with True Nucleus whereas Prokaryotes are not.

1 Prokaryotic cell has no mitochondria

Whereas eukaryotic cell has mitochondria

2.In prokaryotic cells ribosomes are smaller whereas eukaryotic cells consist larger ribosomes.

3.Prokaryotes lack a nucleus whereas nucleus is present in eukaryotes.

Prokaryotic cells have their genetic material (DNA) not enclosed within a nucleus, for example a bacteria has its DNA in plasmids (circular loop of DNA) and strands. Prokaryotic cells also do not have membrane bound organelles (structures within a cell that do not contain a membrane). Prokaryotic cells are much smaller than eukaryotic cells.


Eukaryotic cells have membrane bound organelles and their DNA is enclosed within a Nucleus. Examples of eukaryotic cells are plant cells and animal cells .

Eukaryotic Cells have a ‘true’ nucleus whereas Prokaryotic cells have a circular loop of DNA floating in the cytoplasm.

Eukaryotic Cells only have a cell membrane whereas Prokaryotic Cells also have a cell wall.

Prokaryotic Cells do not have any membrane bound organelles like mitochondria

Prokaryotic Cells can have a flagellum or mucus capsule

Prokaryotes: smaller, circular DNA, no nucleus, 70 S ribosome


Eukaryotes: larger, linear DNA, has nucleus, 80 S ribosome

Prokaryotes are uni-cellular, meaning they a made of just one cell. Eukaryotes can be either unicellular or multicellular. Eukaryotes have a nucleus which contains the genetic material (DNA). Prokaryotes do not have a nucleus, instead their genetic material (DNA) is found in the cytoplasm. Eukaryotes have membrane bound organelles where as the organelles in prokaryotes are not membrane bound. Eukaryotes are also much bigger than prokaryotes. Furthermore, Eukaryotes contain mitochondria which perform respiration, whereas, prokaryotes do not have mitochondria and respiration takes place in the cytoplasm.

Remember a simple difference, Prokaryotes doesn't have nuclear membrane and the organelles are dispersed in cytoplasm while eukaryotes have nuclear membrane and the cellular Organelles are present inside the membrane.

A prokaryotic cell has different genetic and cellular features in comparison to eukaryotic cells. For example, prokaryotic cells have a strand of DNA lying in the chromosome whereas eukaryotic cells have condensed chromosomes in the nucleus. Prokaryotes are always unicellular and most eukaryotes are multi-cellular.

Hello Elizabeth,


Prokaryotic cells where the first to appear on Earth (like a prototype is the first of a phone or a car). Therefore they are simple cells eg Bacteria

Key differences - Pro have an outer Slime capsule, No nucleus but strands of DNA and Plasmids floating in the cytoplasm and Flagella for motility.

Hope this helps.

Animal and plant cells are eukaryotic cells whereas bacteria and yeast cells are types of prokaryotic cells. There are a few main differences between eukaryotic and prokaryotic. One is the size, prokaryotic cells are much smaller than eukaryotic cells. Prokaryotic cells also always have a cell membrane made of peptidoglycan whereas only some types of eukaryotic cells have a cell membrane. Finally, the genetic material for eukaryotic cells are found within the nucleus however for prokaryotic cells the genetic material is found in the cytoplasm.

Prokaryotic cells are Bacteria cells , like yeast. Their unicellular and their nucleus is not membrane bound


Eukaryotic cells include animal cells and plant cells. Their multicellular and membrane bound
