Storyboard Text

  • Today we are talking about internal and external fertilization
  • Internal fertilization is when a female's egg (the ovum) is fertilized inside her body
  • External fertilization is when a female's egg (the ovum) is fertilised on the outside of her body.
  • Fertilization is when the sperm of a male combines with the ovum of a female. Only one is allowed to combine though, and once it has the ovum puts up a block from all the other sperm cells. 
  • Mammals, Birds and Reptiles have internal fertilization. Just like humans.
  • Fish and amphibians usually have external fertilization, but there are some exceptions.
