What is larger than a cell?

Organelles are the substructures (such as mitochondria and chloroplasts) inside cells that perform particular functions. They are therefore smaller than cells. They are therefore larger than cells. Organisms are made up of organs which are made up of tissues, and are therefore larger than tissues.
