Eukaryotes space organisms whose cell possess a cell nucleus enclosed in ~ a cell membrane, consisting of one the the three domain names of life, Eukaryota. They encompass multicellular organisms such as plants, animals, and also fungi.

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

Bacteria and Archaea, the various other two domains of life, space prokaryotic cells. They execute not possess membrane-bound to move compartments, such together nuclei.

Similarities in between eukaryotic and also prokaryotic cells

Cell Membrane

Both eukaryotic and prokaryotic cells bear a lipid bilayer, which is an plan of phospholipids and also proteins the acts together a selective barrier between the internal and external environment of the cell.

Genetic Material

Eukaryotic and also prokaryotic cells both usage deoxyribonucleic acid (DNA) as the basis because that their genetic information. This hereditary material is essential to regulate and inform cell duty through the production of RNA by transcription, followed by the generation of proteins with translation.


Ribosomes facilitate RNA translation and the development of protein, i beg your pardon is necessary to the work of both eukaryotic and also prokaryotic cells.


The cytoplasm is the tool in i beg your pardon the biochemical reaction of the cell take place, of i beg your pardon the major component is cytosol.

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

Differences in between eukaryotic and also prokaryotic cells

Cell size

Eukaryotic cells room ordinarily bigger (10 – 100um) 보다 prokaryotic cells (1 – 10um).

Cell arrangement

Eukaryotes are often multicellular vice versa, prokaryotes space unicellular. There are however some exception –unicellular eukaryotes include amoebas, paramecium, yeast.

True membrane-bound nucleus

Eukaryotic cells have a true nucleus bound by a twin membrane. It includes the DNA-related features of the large cell in a smaller enclosure come ensure nearby proximity the materials and also increased performance for cellular communication and also functions.

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

DNA structure

Eukaryotic DNA is linear and complexed v packaging proteins called "histones," prior to organization right into a number of chromosomes

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

Membrane-bound organelles

Eukaryotic cells contain countless membrane-enclosed, large, complex organelles in the cytoplasm whereas prokaryotes cells execute not contain these membrane-bound organelles.

This is a crucial difference because it allows a high level the intracellular department of labor and also contributes come the greater complexity characteristic of eukaryotic bio cells.

Due come the larger size the the eukaryotic cells, confining certain cellular procedure to a smaller area likewise increases the effectiveness of features by improving communication and also movement within the cell.

Only eukaryotes own a membrane-bound nucleus and membrane-bound oribel such together the mitochondria, golgi apparatus, lysosomes, peroxisomes and ER.

Ribosome size

Both eukaryotic and prokaryotic cells contain many ribosomes; but the ribosom of the eukaryotic bio cells are larger than prokaryotic ribosomes i.e. 80S contrasted to 70S.

Eukaryotic ribosomes also show much more complexity than prokaryotic – lock are created of five kinds of ribosome RNA and around eighty kinds of proteins. In contrast, prokaryotic ribosomes room composed of just three kinds of rRNA and around fifty kinds of protein.


This is a multicomponent device in eukaryotes composed of microtubules, actin filaments and intermediate filaments. The is compelled for maintaining cell shape, providing internal organization and also mechanical support. It is additionally paramount in movement and cell division.

Sexual reproduction

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

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

Cell division

This wake up by mitosis for eukaryotic bio cells and binary fission for prokaryotes cells.

Eukaryotic cell undergo mitosis then cytokinesis. This involves numerous stages - the nuclear membrane disintegrates then the chromosomes are sorted and also separated to ensure the each daughter cabinet receives two sets (a diploid number) of chromosomes. Complying with this, the cytoplasm divides to form two genetically the same daughter cell i.e. Cytokinesis.

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