25 Examples of Unicellular and Multicellular Organisms

The organisms They are living beings that are made up of one or more cells. Cells are the minimum units of life that present different degrees of complexity according to their structure or organization.

Unicellular organisms are those that are made up of a single cell, for example: bacteria and yeasts;multicellular organisms are those that are made up of two or more cells, for example: the shark, the vulture, the eucalyptus.

Unicellular organisms

The single-celled organisms They are microscopic organisms that gather all their vital functions in a single cell. Almost all organisms prokaryotes (which have cells without a cell nucleus) and some organisms eukaryotes (which have cells with a cell nucleus) are unicellular.

Inside of the monera kingdom all bacteria are unicellular organisms, for example: scherichia coli, salmonella typhi and all archaea, for example: themethanogenic archaea. Inside of the fungi kingdom, yeasts, for example: pichia, saccharomyces cerevisiae (brewer's yeast); inside of the protist kingdom, protozoa, for example: paramecium and dinoflagellates.

Multicellular organisms

The multicellular organisms They are made up of two or more cells that specialize in different vital functions (neurons, epithelial cells, red blood cells). These specialized cells form tissues that in turn make up the organs of the living being.

All the animals Y plants are multicellular organisms, for example: mammals like the lion, amphibians like the frog, trees like oak, herbaceous like onion. Some mushrooms and some organisms of the protist kingdom are also multicellular, for example: mushrooms, algae.
