Multicellular Organism
Multicellular organisms are organisms that consist of more than one cell, in contrast to single-celled organisms. To form a multicellular organism, these cells need to identify and attach to the other cells.
Only a dozen or so species of life that can be seen with the naked eye are unicellular. The rest of the nearly two million visible species are multicellular. In particular all but one or two species of the million and a half animals are multicellular, as well as many plants and fungi. Some organisms are partially uni- and multicellular, like Dictyostelium.

Famous quotes containing the word organism:
“The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are fallingwhat can be done?... Nothing can be done, and nothing needs to be done. Something is being donethe organism is preparing to rest.”
—David Mamet (b. 1947)
