Basic Info for Ch 46

Ch 46 – Animal Reproduction

1. What is the difference between sexual and asexual reproduction?
2. What are the advantages and disadvantages of each (sexual and asexual)?
3. Go to the textbook website: http://wps.aw.com/bc_campbell_biology_8ap/ , and go to Ch 46. Under concept 46.3, go through “Activity: Reproductive System of the Human Female” and “Activity: Reproductive System of the Human Male”. For both, you should know the structures and their functions. Pay special attention to what substances are produced and what structures produce and transport them. Take notes. [Hopefully this is largely review, but if not, these animations are not easily forgotten!]
4. Compare and contrast oogenesis and spermatogenesis (figure 46.11 is a big help with this).
5. Connect back to Ch 45! Regulation of the ovarian and menstrual cycles by multiple hormones is an important example to know. Reread section 46.4, and make yourself a table with the female hormones described in the section. In the table, include each hormone, where it is produced, its target(s), its action (effect) at the target, and its regulation (what regulates its production/secretion, in other words, what it is produced or secreted in response to). [The activity on the female reproductive system – question 3 above – also gives details that will be useful.]
6. Connect back to Ch 40 again! Explain how the process of labor, including the role of oxytocin, is an example of positive feedback.

** Although questions 3-6 refer to mammalian (specifically, human) systems, don't overlook the systems and adaptations of other animal groups also discussed in this chapter - include a bit about these in your notes.
