What is the term for the stage when cells divide to create two to four new cells?

1. Metaphase

2. Prophase

3. Telophase

4. Anaphase

The correct answer is: Telophase

The stage when cells divide to create two to four new cells is known as telophase. During this phase of cell division, specifically in mitosis, the chromosomes that have been duplicated during the earlier stages begin to de-condense back into chromatin, and the nuclear membrane reforms around each set of chromosomes. This marks the final stage of cell division, leading to the completion of the process as the cell prepares to separate into daughter cells. Understanding the roles of the other stages helps clarify why telophase is the correct choice. Metaphase is when chromosomes align at the cell's equatorial plane, prophase refers to the initial formation of the chromosomes and disappearance of the nuclear envelope, and anaphase involves the separation and movement of chromosomes to opposite poles of the cell. Each of these stages precedes telophase, solidifying it as the correct term for the stage where the actual division into new cells occurs.
