Levels of Organization In unicellular (single-celled) organisms, the single cell performs all life functions. It functions independently. However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions (causing a division of labor) and work together for the good of the entire organism. The cells become dependent on one another. Explore Cells, Tissues, Organs, Organ Systems, and Organisms.
