Here's a breakdown of the levels of organization:
* Atom: The smallest unit of an element that retains the chemical properties of that element.
* Molecule: Two or more atoms bonded together.
* Organelle: A specialized structure within a cell that performs a specific function.
* Cell: The basic unit of life.
* Tissue: A group of similar cells working together to perform a specific function.
* Organ: A structure made up of different tissues that work together to perform a specific function.
* Organ System: A group of organs that work together to perform a specific function.
* Organism: A complete living being.
So, while an organelle is part of a cell, it's still a larger structure than a molecule.
