Here's why:

* Meiosis is a type of cell division that produces gametes, which are specialized reproductive cells (like sperm and egg in animals, or pollen and ovules in plants).

* Sexual reproduction involves the fusion of two gametes (fertilization) to create a new, genetically unique individual.

So, any organism that reproduces sexually uses meiosis to create the gametes needed for this process. This includes:

* Animals (mammals, insects, fish, etc.)

* Plants (flowering plants, trees, etc.)

* Fungi

* Many algae
