Plant and Animal Organ Systems

The video explains the structure of multicellular organisms, highlighting the five levels of organization: cells, tissues, organs, organ systems, and organisms. It describes how cells, the basic building blocks, form tissues, which then form organs and organ systems. The video uses examples like the palisade mesophyll cell and leaf organ to illustrate these concepts, emphasizing the cooperation and specialization of cells and tissues in both plants and animals.
