When I was learning the difference between mitosis and meiosis, I remembered it by thinking about their purposes. Mitosis is what my body uses to grow and heal—one cell splits into two identical cells. Meiosis, on the other hand, is how I’d pass on my genes—it’s used to create sex cells, like eggs or sperm, and ends up with four cells that each have half the number of chromosomes. Keeping their goals in mind helped me remember which is which!
