See below.

Work Step by Step

Similarities: Both are energy-releasing nuclear reactions that involve the transmutation of elements. Differences: Fission involves splitting heavy nuclei, and fusion involves joining light nuclei. Fission requires a critical mass for a self-sustaining chain reaction, but there is no such analogue for fusion. Finally, fusion requires high temperatures (for now).
