Fun Fact

A human body contains trillions of cells, and each type has a different job. Some cells carry oxygen, some send signals, and others help protect the body. Even though cells are microscopic, they work together to keep an entire human being functioning.

One especially famous biology fact is that mitochondria are often called the “powerhouses of the cell” because they produce much of the cell’s usable energy. That makes mitochondria perfect material for jokes—and these puns are ready to divide and multiply!
