Every day, every hour, every second one of the most important events in life is going on in your body—cells are dividing. We call this process "cell division" and "cell reproduction, " because new cells are formed when old cells divide.

C. daughter cells that are identical to the parent cell. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. Each of these methods of cell division has special characteristics.

DNA (deoxyribonucleic acid): molecular instructions that guide how all living things develop and. Somatic cells make up most of your body's tissues and organs, including skin, muscles, lungs, gut, and hair cells. Cells also divide so living things can grow.

During meiosis, a small portion of each chromosome breaks off and reattaches to another chromosome. Students also viewed. In cell division, the cell that is dividing is called the "parent" cell. The Golgi apparatus, however, breaks down before mitosis and reassembles in each of the new daughter cells.
