External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined.
In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.
Fertilization in animals refers to the point where a sperm meets an egg. External fertilization means the sperm and eggs meet outside the animals, usually in the water. So a male and female fish can swim alongside each other and while the female releases her eggs the male will release his sperm. Certain male fish have a specialized fin shaped like a tube. They stick that in a pore in the female and put their sperm into the female. The sperm fertilizes the eggs inside the female. That is called internal fertilization. Fish use both internal and external fertilization depending on the type of fish.

Internal fertilization is where the egg is fertilized inside the body(such as humans) and external fertilaztion is where the an egg is laid and then fertilized. Such as in fishes!
