| 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. |
