Definition

A small structure within cells that helps produce energy by converting food into a usable form. It is found in almost all eukaryotic cells and contains its own genetic material.

Example

The mitochondrion is often referred to as the powerhouse of the cell because it generates most of the cell's supply of adenosine triphosphate (ATP).

Conversation

I just learned about the mitochondrion in my biology class.

Really? What does it do?

It helps produce energy for the cell through cellular respiration.

That's cool! I didn't know it was so important for our cells.

Synonyms & Antonyms

Root Explanation

Mitochondrion → It is formed from "mitos" (from Greek, meaning thread) and "chondrion" (from Greek "chondros", meaning granule or grain). The word refers to the thread-like structures that are granules within the cell, known for their role in energy production.

Memory Tip

Imagine thread-like structures ('mitos') that are like tiny granules ('chondrion') in your cells, helping to produce energy. This helps you remember that mitochondrion refers to these energy-producing threads.
