🇬🇧 Mitochondria meaning: English Vocabulary Flash Card

Mitochondria are tiny parts inside almost every cell in your body that work like mini power plants. They take the food you eat and the oxygen you breathe and turn them into energy that the cell can use to move, grow, and stay alive. Because they make so much energy, people sometimes call mitochondria the “powerhouses of the cell.”

My mitochondria must be morning people, because my energy always disappears after lunch.

I told my mitochondria I was going to sprint; they immediately looked for the emergency exit.

During math class, my mitochondria switched to low‑power mode to save energy for recess.
