# Organisms

Organisms are groups of molecules (and possibly atoms) joined together to form distinct section of an interface.

Organisms can consist of similar and/or disparate molecule types. For example, a masthead organism might consist of a logo, navigation, and search form, while a ‘product grid’ organism might consist of the same product info molecule repeated over and over.

Building up from molecules to organisms encourages creating standalone, portable, reusable components.
