Mitosis and meiosis both require cells dividing to produce new cells. This presents them both as essential processes for the survival of breathing things that propagate sexually. Meiosis produces the cells required for sexual procreation to transpire, and mitosis replicates non-sex cells required for growth and maturation. Together, they give the cellular foundation for healthy growth and sexual reproduction.
