* Animals: All animals, from insects to humans, undergo meiosis to produce gametes (sperm and egg cells).

* Plants: Plants use meiosis to produce spores, which then develop into gametophytes that produce gametes.

* Fungi: Many fungi reproduce sexually, using meiosis to produce spores.

* Protists: Some protists undergo meiosis as part of their sexual reproduction cycles.

Essentially, any organism that relies on the fusion of two gametes to produce offspring will utilize meiosis as a key step in their life cycle.
