What is the correct sequence for organizing living things from smallest to largest?

The correct sequence for organizing living things from smallest to largest is organelle, cell, tissue, organ, organ system, and organism.

This hierarchy reflects the structural organization within biological systems. Organelles, such as mitochondria and ribosomes, are the smallest functional units within a cell, responsible for various activities essential for life. When organelles combine to form a cell, that cell becomes the basic unit of life. Groups of similar cells then combine to form tissues, which serve specific functions. Multiple types of tissues gather to create organs, which carry out more complex functions for the organism. Organs work together in organ systems to perform critical functions. Finally, all of the organ systems collectively constitute an organism, representing the highest level of biological organization.

Understanding this hierarchy is crucial as it illustrates the complexity and interdependence of biological structures, helping to explain how life is organized and functions.
