Organismong multiselular

The nematode Caenorhabditis elegans stained to highlight the nuclei of its cells

Ang isang organismong multiselular ay isang organismo na binubuo ng higit sa isang selula at salungat sa organismong uniselular.[1]

Ang lahat ng mga espesye ng mga hayop, mga Embryophyte(halamang panglupain) at karamihan ng fungi ay multiselyular gaya ng maraming mga algae samantalang ang ilang mga organismo ay bahaging uniselyular at bahaging multiselyular gaya ng mga slime mold at mga genus ng amoebae gaya ng Dictyostelium.[2][3]

Ang mga organismong multiselular ay lumilitaw sa maraming paraan halimbawa, sa dibisyon ng selula o sa pagsasama ng maraming mga isang selula.[4][3] Colonial organisms are the result of many identical individuals joining together to form a colony. However, it can often be hard to separate colonial protists from true multicellular organisms, because the two concepts are not distinct; colonial protists have been dubbed "pluricellular" rather than "multicellular".[5][6] Mayroon ring mga multinucleate bagaman ang mga teknikal na organismo na makroskopiko gaya ng xenophyophorea ay umaabot na 20 cm.
