The document outlines the different levels of organization in living things from smallest to largest: cells, tissues, organs, organ systems, and organism. Cells are the basic unit of life and come together to form tissues. Tissues join together to create organs, organs combine to form organ systems, and organ systems work as a whole to comprise an organism, the single living thing. Each level builds upon the previous to perform specialized functions and keep the organism alive.
