What is the external and internal fertilisation of the embryo?
External vs Internal Fertilization Of The Embryo
When we come to the biological world of reproduction, there are many ways of reproduction among organisms. These include budding, binary fission, spores, asexual, and sexual. There are other methods, too. Among these, the sexual mode of reproduction includes a fusion of gametes. Gametes are eggs from the female and sperm from the male. Only the successful fusion between egg and sperm will lead to the formation of a zygote. Which is the first stage of life? This mode can happen in two ways. One method is internal fertilization, and the other is external fertilization. In the internal fertilization method, the sperm and ova (egg) get fertilized inside the maternal body. To be frank, fertilization happens inside the ovum. This mode of reproduction is seen in humans. The other mode is external fertilization. In this method, fertilization happens outside the female body. This type of fertilization is seen in frogs. Both internal and external fertilization play a major role in maintaining the equilibrium of the ecosystem
