Levels of Organization The living world can be organized into different levels. For example, many individual organisms can be organized into the following levels:
Cell: Basic unit of structure and function of all living things. Tissue: Group of cells of the same kind. Organ: Structure composed of one or more types of tissues. The tissues of an organ work together to perfume a specific function. Human organs include the brain, stomach, kidney, and liver. Plant organs include roots, stems, and leaves. Organ system: Group of organs that work together to perform a certain function. Examples of organ systems in a human include the skeletal, nervous, and reproductive systems. Organism: Individual living thing that may be made up of one or more organ systems.
