Levels of Organization in Multicellular Organisms

Mr. Miller explains the concept of division of labor in organisms, focusing on multicellular organisms. He describes the five levels of organization: cells, tissues, organs, organ systems, and the organism itself. Each level has a specific function, contributing to the organism's survival. The video covers unicellular and multicellular organisms, highlighting the complexity and cooperation within multicellular organisms.
