No – it’s not a picture of a sunflower.  Look closely!

Here is what we will cover in the core material.

  • Draw and label diagrams of adult male and female reproductive systems.
  • How do hormones control the menstrual cycle? (Link to Endocrine system)
  • Relate hormonal changes to thickening of uterine lining, ovulation and menstruation.
  • What are the roles of testosterone in males?
  • Explain the process of IVF and discuss the ethical issues associated with it.

A good presentation can be found here.  Some great videos on this unit have been produced by NOVA.  Watch in segments or all at once.

Higher level material in this presentation.  We need to learn the details of spermatogenesis and oogenesis.  Your textbooks are pretty good on this as well, so read the relevant chapters.  We’ll get into the processes of fertilization, pregnancy and childbirth.

We covered the basics last semester – now on to the detailed HL stuff to do with reproduction.  Check out this presentation, which has good information and some great links to explore.

We’ll start by reviewing the stucture of egg and sperm. then look at how they are produced.  You can read up on the processes of spermatogenesis and oogenesis in your textbooks on pages 265/6.  We’ll take a more detailed look at the process of fertilization, pregnancy and childbirth.

You can also use this powerpoint from Mr Hobbins 🙂 Reproduction Higher
