Cell Division: Growth and Repair
Learning Objective
I can model the process of cell division and its importance in growth and repair.
Key Concepts
Mitosis is a type of cell division that is important for growth and repair of body cells, but it does not produce sperm or egg cells.
Before mitosis begins, the cell duplicates its DNA during interphase so that each new cell will have the same genetic information.
The four stages of mitosis are prophase, metaphase, anaphase, and telophase, which can be remembered using the acronym PMAT.
Practice Questions
This lesson includes 3 practice questions to reinforce learning.

1. Mitosis results in two identical cells. Explain why maintaining identical DNA in these new cells is crucial for the proper functioning of an organism.
2. During which phase of the cell cycle does DNA replication occur, and why is this phase critical for successful mitosis?
3. Which of the following accurately describes the arrangement of chromosomes during metaphase?
