Origins & Early Life
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a zygote and initiate its development into a new individual organism or offspring. While processes such as insemination or pollination, which happen before the fusion of gametes, are also sometimes informally referred to as fertilisation, these are technically separate processes. The cycle of fertilisation and development of new individuals is called sexual reproduction.
Career & Major Achievements
During double fertilisation in angiosperms, the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. In antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic.
Enduring Legacy & Impact
In 1784, Spallanzani established the need of interaction between the female's ovum and male's sperm to form a zygote in frogs. In 1827, Karl Ernst von Baer observed a therian mammalian egg for the first time.
Chronological Milestones & Life Events
Historical Fact-Check Quiz: Fertilization
True or False: “The initial formation of a zygote always requires the physical fusion of male and female gametes.”
Answer (FALSE ❌): While fusion is the primary mechanism, some processes like parthenogenesis can lead to zygote-like development without the direct combination of gametes.
