The first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
- The events in this stage of the cell cycle leading to cell division are prophase, metaphase, anaphase and telophase.

- These questions asked the reader to describe and draw the cell when it was in the telophase and the late prophase stages of mitosis.
