Cell division is the process by which a cell divides into two daughter cells. This is a critical process in all living organisms as it allows for growth, development, and repair of tissues. Cell division is tightly regulated to ensure that each daughter cell receives the correct amount of genetic material and organelles. There are two main types of cell division: mitosis, which produces two identical daughter cells with the same number of chromosomes as the parent cell, and meiosis, which produces four daughter cells with half the number of chromosomes as the parent cell. Understanding the mechanisms of cell division is important for understanding diseases such as cancer, where uncontrolled cell division can lead to tumor formation.
