All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium. [2] [3] Multicellular organisms arise in various ways, for example by cell division or by aggregation of many single ...
Animals are multicellular eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (/ ˌ æ n ɪ ˈ m eɪ l i ə / [4]).With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.

Metazoa, known as animals, are multicellular organisms that sum more than 1.5 million living species. [14] They are characterized by a blastula phase during their embryonic development and, except for the amorphous sponges, the formation of germ layers and differentiated tissues. [4]
In this system the multicellular animals are descended from the same ancestor as both the unicellular choanoflagellates and the fungi which form the Opisthokonta. [45] Plants are thought to be more distantly related to animals and fungi.
A life form (also spelled life-form or lifeform) is an entity that is living, [1] [2] such as plants , animals , and fungi . It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, [3] are extinct. [4] [5] Earth is the only celestial body known to harbor life forms. No form of ...
The multicellular eukaryotes include the animals, plants, and fungi, but again, these groups too contain many unicellular species. [11] Eukaryotic cells are typically much larger than those of prokaryotes —the bacteria and the archaea —having a volume of around 10,000 times greater.
