- If a cell keeps growing, why must it eventually divide?
- What factors limit the size of a cell?
- Define the surface area to volume ratio. Provide context to cell division.
- What potential problems of a cell are solved by cell division?
- What are the advantages and disadvantages of both asexual and sexual reproduction?
- Aphids are a type of insect. They reproduce asexually in the spring and summer. They reproduce sexually in the fall. How might this pattern improve the species' chances of survival?
- How are the chromosomes in eukaryotic cells different from those in prokaryotic cells?
- What is the cell cycle?
- What events occur during interphase?
- What structures are responsible for the movement of chromosomes to the center of the cell in metaphase and their separation in anaphase?
- Describe what happens during each of the four phases of mitosis.
- Launch the interactivity in the Cytokinesis section. Summarize the process described in the video.
- Why must multicellular organisms tightly control the cell cycle?
- Name the two types of proteins that regulate the cell cycle. How do these proteins work?
- Why is the presence of cancer cells so harmful to the body?
- Why is cancer considered a disease of the cell cycle?
- How does a single fertilized egg cell develop into so many different types of specialized cells?
- What are stem cells? How are embryonic stem cells different from adult stem cells?
- What do the arguments for and against the use of stem cells in medical research share?
- Why is cell differentiation essential for every complex multicellular organism?
