📚 Part 1: Mitosis Process

1. During which phase of mitosis do chromosomes line up at the center of the cell?

Prophase

Metaphase

Anaphase

Telophase

2. What is the main purpose of mitosis in multicellular organisms?

To create genetic diversity

To produce gametes

To grow and repair tissues

To reduce chromosome number

3. How many chromosomes will each daughter cell have after mitosis in a human cell?

23 chromosomes

46 chromosomes

92 chromosomes

It varies

4. Which structures are responsible for moving chromosomes during mitosis?

Centrioles and spindle fibers

Ribosomes and endoplasmic reticulum

Mitochondria and chloroplasts

Nucleus and cytoplasm

🧬 Part 2: DNA and Traits

5. Complete the sentence: DNA contains the _____________ for making proteins that determine an organism's traits.

6. Explain how DNA in chromosomes codes for traits. Use the terms "genes," "proteins," and "characteristics" in your answer.

7. Why is it important that DNA is copied exactly during mitosis?

8. A parent cell has DNA that codes for brown eyes. After mitosis, what eye color will the daughter cells code for? Explain your reasoning.

🎯 Part 3: Connecting Concepts

9. Draw and label a simple diagram showing how one parent cell becomes two identical daughter cells through mitosis. Include chromosomes in your drawing.

10. Extension Challenge: How might errors in mitosis affect the traits of daughter cells? Predict what could happen if chromosomes don't separate properly.
