WebThis idea was based on the observation that after a stroke, the brain undergoes a process called gliosis, whereby the supporting cells in the brain (glial cells) proliferate and replace neurons that have died during the hypoxic (stroke) episode. Web1. Cell division is the only way single-celled organisms can reproduce. Multicelled organisms need cell division to grow and replace dead or damaged cells. 2. After growth, the division remains important in normal cell turnover, such as in our skin and gut, where cells are continuously removed.

Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
