Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction. Use the diagram to identify one similarity and one difference between mitosis and meiosis. Your answer must specifically refer to this diagram. [i.e. say what specific cells in the diagram show the similarity or difference] Mitosis Parent cell Meiosis Parent cell DNA replicates DNA replicates 2 daughter cells 2 daughter cells 4 daughter cells U.S. National Library of Medicine

Question
### Cell Division: Mitosis vs. Meiosis

**Introduction**

Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction.

**Diagram Analysis**

Here is a visual representation of cell division processes: mitosis and meiosis. The diagram includes both processes, allowing us to compare and contrast them.

**Mitosis**

In mitosis, the process begins with a parent cell. The DNA within this parent cell replicates, creating an identical copy. This replication results in the formation of two daughter cells, each with an identical set of chromosomes. The key steps in mitosis depicted are:

- **Parent Cell**: The starting cell.
- **DNA Replication**: The genetic material duplicates.
- **2 Daughter Cells**: The final result, producing two identical cells.

**Meiosis**

Meiosis starts similarly with a parent cell, where DNA replicates. However, unlike mitosis, meiosis undergoes two rounds of cell division, resulting in four daughter cells, each with half the number of chromosomes of the parent cell. The meiotic process is illustrated as follows:

- **Parent Cell**: The starting cell.
- **DNA Replication**: The genetic material duplicates.
- **First Division**: Produces two daughter cells.
- **Second Division**: Each of these two cells divides again, resulting in a total of four non-identical daughter cells.
- **4 Daughter Cells**: The end result, producing four genetically diverse cells.

**Comparison**

To identify one similarity and one difference between mitosis and meiosis:

**Similarity**:
- Both processes start with a parent cell and involve DNA replication. Specifically, both the mitosis and meiosis diagrams show a parent cell (topmost cell in each diagram) that undergoes DNA replication (second layer of cells in each diagram).

**Difference**:
- Mitosis results in two daughter cells that are genetically identical to the parent cell (final step in the mitosis diagram), while meiosis results in four daughter cells that are genetically diverse and have half the number of chromosomes compared to the parent cell (final step in the meiosis diagram).

**Level 3 Summary**

This diagram helps to understand the fundamental differences and similarities in the processes of mitosis and meiosis, illustrating the purpose and outcome of each type of cell division.
