Mitosis vs. Meiosis
Worksheet
1. We know that cells divide and reproduce in two ways: mitosis and meiosis. Mitosis consists of
only one cell division whereas meiosis consists of two cell divisions. Play each animation. Use
the Notes to label which animation you think is mitosis and which one you think is meiosis. Take
a photo.
2. Let's look at the first stage of both mitosis and meiosis: Prophase. Compare Prophase during
mitosis with Prophase I during meiosis. How are they similar? How are they different?
3. Crossing over occurs only during meiosis, after Prophase I and before Metaphase I. Crossing
over never occurs during mitosis. Crossing over is the process where non-sister chromatids pair
up with each other and exchange different segments of genetic information. Explain why you
think this process would be important for meiosis cell division but not important for mitosis cell
division.
