- 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
