WebIn plant cells, the first part of mitosis is the same as in animal cells. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Then, where an animal cell would go through cytokineses, a plant cell simply creates a new cell plate in the middle, creating two new cells. The cell plate later changes to a cell wall once the division is complete.

WebThe gamete cell cycle is called meiosis and is a topic of Bio 181. Interphase represents cell growth and where DNA is replicated, mitosis represents cell division. Cells will cycle through interphase then mitosis and back to interphase. The most important result of the cell cycle is the replication (copying) and movement of the DNA. WebThe four periods G , S, G, and M (for mitosis) make up the cell division cycle. The cell cycle characteristically lasts between 10 and 20 hours in rapidly proliferating adult cells, but it can be arrested for weeks or months in quiescent cells.
