Investigation 1: PostLab
Focus Questions:
Think about the following questions as we work through today’s PreLab. By the end of this Investigation, you should be able to answer each one confidently.
1. What role do chromosomes play in human development?
2. Why do humans have 23 pairs of chromosomes, and why does this matter for growth?
3. How does mitosis allow a tiny embryo to grow into a full-term baby?
4. What do the different stages of mitosis reveal about how cells divide accurately?
5. Why are chromosome mistakes during early development so serious?
Think Critically:
What are the major differences between asexual and sexual reproduction? In your answer, describe both the advantages and disadvantages of asexual and sexual reproduction. Do humans reproduce asexually or sexually?
Why is it important that each new cell gets an exact copy of the DNA during mitosis?
How do chromosomes ensure that genetic information is accurately passed from one cell to another during cell division?
How does mitosis help organisms grow and heal?
