Cell division is a process where one cell splits into two new cells. It is a part of a larger cell cycle. This is very important for your body because it helps in three main ways: 1. Growth – Making Your Body Bigger When you were a baby, you were much smaller than you are now. Your body grew because your cells kept dividing and increasing in number. More cells mean bigger bones, muscles, and organs! 2. Repair and Healing – Fixing Damaged Parts If you get a cut or scrape, your body heals because cell division creates new skin cells to replace the damaged ones. The same happens inside your body when organs or tissues need repair. 3. Reproduction – Creating New Life For humans, special cell division (called **meiosis**) helps create sperm and egg cells. These cells are needed for reproduction, so new human life can begin.
