Eukaryotes room organisms whose cell possess a nucleus enclosed in ~ a cell membrane, consisting of one of the three domains of life, Eukaryota. They include multicellular organisms such together plants, animals, and also fungi.

You are watching: Which three structures are found in both prokaryotic and eukaryotic cells?

Bacteria and also Archaea, the other two domains of life, space prokaryotic cells. They do not possess membrane-bound moving compartments, such together nuclei.

Similarities in between eukaryotic and also prokaryotic cells

Cell Membrane

Both eukaryotic and also prokaryotic cell bear a lipid bilayer, i m sorry is an plan of phospholipids and also proteins that acts as a selective barrier between the internal and external atmosphere of the cell.

Genetic Material

Eukaryotic and also prokaryotic cells both use deoxyribonucleic mountain (DNA) as the basis because that their genetic information. This genetic material is necessary to regulate and also inform cell duty through the creation of RNA by transcription, complied with by the generation the proteins with translation.


Ribosomes facilitate RNA translation and the creation of protein, i beg your pardon is important to the functioning of both eukaryotic and also prokaryotic cells.


The cytoplasm is the tool in i m sorry the biochemical reactions of the cell take it place, of i beg your pardon the primary component is cytosol.

In eukaryotic bio cells, the cytoplasm comprises everything between the plasma membrane and the nuclear envelope, consisting of the organelles; the material within the cell nucleus is termed the nucleoplasm. In prokaryotes the cytoplasm encompasses everything in ~ the plasma membrane, consisting of the cytoskeleton and also genetic material.

Differences in between eukaryotic and prokaryotic cells

Cell size

Eukaryotic cells room ordinarily larger (10 – 100um) than prokaryotic cells (1 – 10um).

Cell arrangement

Eukaryotes are frequently multicellular whereas prokaryotes are unicellular. Over there are however some exceptions –unicellular eukaryotes include amoebas, paramecium, yeast.

True membrane-bound nucleus

Eukaryotic cells have actually a true nucleus bound by a twin membrane. It includes the DNA-related attributes of the large cell in a smaller enclosure to ensure nearby proximity the materials and increased effectiveness for moving communication and also functions.

In contrast, the smaller sized prokaryotic cells have no nucleus. The materials are already reasonably close to every other and also there is just a "nucleoid" i m sorry is the main open an ar of the cell where the DNA is located.

DNA structure

Eukaryotic DNA is linear and complexed through packaging proteins called "histones," before organization right into a variety of chromosomes

Prokaryotic DNA is circular and also is neither associated with histones no one organized right into chromosomes. A prokaryotes cell is simpler and also requires far fewer gene to function than the eukaryotic bio cell. Therefore, it contains only one one DNA molecule and also various smaller sized DNA circlets (plasmids).

Membrane-bound organelles

Eukaryotic cells contain plenty of membrane-enclosed, large, facility organelles in the cytoplasm whereas prokaryotes cells execute not contain this membrane-bound organelles.

This is a vital difference because it permits a high level of intracellular department of labor and contributes to the greater complexity characteristic of eukaryotic cells.

Due come the larger size that the eukaryotic bio cells, confining details cellular procedure to a smaller area likewise increases the effectiveness of functions by boosting communication and also movement within the cell.

Only eukaryotes possess a membrane-bound nucleus and membrane-bound oribel such as the mitochondria, golgi apparatus, lysosomes, peroxisomes and also ER.

Ribosome size

Both eukaryotic and prokaryotic cells contain countless ribosomes; but the ribosom of the eukaryotic cells are larger than prokaryotes ribosomes i.e. 80S compared to 70S.

Eukaryotic ribosomes also show much more complexity 보다 prokaryotic – lock are built of five kinds of ribosome RNA and around eighty kinds of proteins. In contrast, prokaryotic ribosomes space composed of only three type of rRNA and about fifty type of protein.


This is a multicomponent device in eukaryotes composed of microtubules, actin filaments and also intermediate filaments. That is compelled for keeping cell shape, giving internal organization and also mechanical support. The is likewise paramount in movement and also cell division.

Sexual reproduction

Most standard scale undergo sex-related reproduction whilst prokaryotes reproduce asexually. Sexual reproduction in eukaryotes results in offspring with genetic material i beg your pardon is a mixture the the parents’ genome and during this process, hereditary variation is produced via sex-related recombination.

On the various other hand, a prokaryote will certainly reproduce clones of chin via binary fission and relies an ext on horizontal genetic transfer because that variation.

Cell division

This occurs by mitosis for eukaryotic bio cells and also binary fission for prokaryotes cells.

Eukaryotic cell undergo mitosis then cytokinesis. This involves countless stages - the atom membrane disintegrates then the chromosomes are sorted and separated come ensure the each daughter cabinet receives 2 sets (a diploid number) the chromosomes. Adhering to this, the cytoplasm divides to type two genetically the same daughter cell i.e. Cytokinesis.

In contrast, prokaryotes experience a simpler process of binary fission. This is quicker than mitosis and also involves DNA (nucleoid) replication, chromosomal segregation, and also ultimately cell separation right into two daughter cells genetically identical to the parent cell. Unlike mitosis, this process does no involve the atom envelope and also centromere and also spindle formation.
