An element or part that composes something; a component.
From Latin composans (present participle of componere, 'to compose'). This botanical and scientific term specifically describes the constituent parts of something composite.
In botany, composant is used to describe the individual florets (tiny flowers) that make up a single 'flower' like a daisy or sunflower—what looks like one flower is actually a whole colony, each composant playing its part!
