Prokaryotische versus eukaryotische cellen

Prokaryotic and eukaryotic cells differ significantly in structure and function.

Prokaryotic cells, such as bacteria and archaea, are simple and lack membrane-bound organelles, including the nucleus.

They are typically unicellular and small, ranging from 0.1 to 5.0 micrometers in length.

Their genomes comprise a single, circular DNA molecule in the nucleoid region.

Prokaryotes have 70S ribosomes, which are smaller compared to eukaryotic ribosomes.

They have simpler internal structures, which allow for rapid growth and reproduction, often through binary fission.

Conversely, eukaryotic cells, found in plants, animals, fungi, and protozoa, are more complex.

They contain membrane-bound organelles like the nucleus, mitochondria, and endoplasmic reticulum that allow compartmentalization of cellular functions.

They have large genomes made of linear DNA stored in the nucleus.

Eukaryotic cells measure 10 to 100 micrometers or more and may form multicellular organisms with specialized cell types for complex biological functions.

They also have the larger 80S ribosomes, reflecting their complex protein synthesis machinery.
