Mitochondria

/ˌmaɪtəˈkɑːndriə/ noun

Definition

Mitochondria are tiny structures inside cells that act like power plants, turning food into usable energy. They are essential for keeping cells, and therefore your whole body, alive and active.

Etymology

From Greek “mitos,” meaning “thread,” and “khondrion,” meaning “little grain,” describing how they looked as threadlike or grainy under early microscopes. The term was coined in the late 19th century as cell biology advanced.

Kelly Says

Mitochondria famously get called the ‘powerhouse of the cell,’ but the wild part is that they were once free-living bacteria that joined our cells in a permanent partnership. You’re basically powered by ancient microscopic immigrants living inside your cells.
