What Is a Many Celled Organism Called?

Organisms with many cells are known as multicellular organisms. Examples of multicellular organisms include animals, plants and fungi. Each of these kingdoms have specialized cell types that separate themselves from undifferentiated unicellular organisms.

Multicellular organisms are composed of a variety of cell types. Humans are, for example, characterized by nerve cells, blood cells, skin cells and muscle cells. This contrasts with unicellular organisms that only have one type of cell.

Animal, plant and fungal cells are all different. Plant cells have chloroplasts, which are required for photosynthesis. Fungal cells have a robust cell wall like plant cells but no chloroplasts. Animal cells have no cell wall but have the capacity for locomotion.
