  • control system
    • sperm cell
      • tail: to propel the sperm to fertilise the egg
      • mitochondria: sperm have many of these cell components, which are the major site of respiration, to produce energy for their journey.
      • haloid nucleus: contains only one set of the genetic material
      • acrosome: contains enzymes to allow the sperm to penetrate the outer layer of the egg.
    • egg (Ovum) cell
      • this is one of the largest cells in the human body and it can be seen without using a microscope.
      • haploid nucleus: contains only one set of the genetic materail.
      • cell membrane: immediately after fertilisation this changes to stop the entry of other sperm
      • cytoplasm: contains the nutrients and mitochondia needed for mitosis
    • egg donations
    • in vitro fertilisation (IVF)
      • test tube babies
    • in vitro
    • surrogate mothers
    • using FSH
      • FSH is given to some women who are having difficulties conceiving, particularly those with low FSH levels. this increases their fertility by simulating the maturation of eggs.
      • FSH is also given to egg donors to trigger the muturation of their eggs in the run up to the operation
