Internal and External Fertalization
Types of fertilization:
Internal fertilization takes place in a female body. However, external fertilization takes place where a sperm cell is united with an egg cell which is external to the bodies that are reproducing individually.
Internal reproduction:
~ better reproduction success
~ protects organisms while they are young
~ the number if off springs are limited
External reproduction:
~ many offspring aren't able to make it through all the different stages
~ the offsprings aren't protected
~ there is a large number of offsprings
