AP Biology: Cell Communication and Reproduction

Essential Questions: Cell Division

What are the steps involved in mitosis and cytokinesis?

How do cells tranfer genetic information (without error) to new cells?

What happens when errors do occur in this process?

10: Cell Reproduction

Be able to draw / label a diagram of mitosis
Compare cytokinesis of plant cells to animal cells
Illustrate how mitosis results in identical daughter cells with the same number of chromosomes as the parent cell.
Identify specific structures within the cell that are involved in cell division.
Draw chromosomes (and alleles) at different stages of the cell cycle
Discuss the importance of HeLa cells in biological research as well as ethical considerations regarding their use.
Explain why cancer is largely a disease of the cell cycle. Discuss reasons that it will be difficult to cure cancer.

11: Meiosis and Life Cycles

Predict how many chromosomes, chromatids, and copies of a given gene will be in a cell at different stages of meiosis
Draw chromosomes (and alleles) at different stages of meiosis
Explain how meiosis produces genetic variation
Contrast the mecahnisms and outcome of meiosis and mitosis
Differentiate between sexual and asexual reproduction
Interpret generaized life cycles of eukaryotic organisms
