===Allogamy===
{{Main|Allogamy}}

Allogamy is the fertilization of flowers through cross-pollination, this occurs when a flower's ovum is fertilized by spermatozoa from the pollen of a different plant's flower.<ref>{{cite web |title=Allogamy |url=https://www.biologyonline.com/dictionary/allogamy |website=Biology Online |access-date=20 August 2022 |date=7 October 2019 |archive-date=25 September 2021 |archive-url=https://web.archive.org/web/20210925025751/https://www.biologyonline.com/dictionary/allogamy |url-status=live }}</ref><ref name="plant systematics">{{cite book |last1=Simpson |first1=Michael G. |title=Plant systematics |date=2019 |publisher=Academic Press |location=Burlington, MA |isbn=978-0128126288 |pages=595–606 |edition=3rd |chapter-url=https://www.sciencedirect.com/science/article/pii/B9780128126288500134 |chapter=13 – Plant Reproductive Biology |access-date=2022-08-20 |archive-date=2022-08-20 |archive-url=https://web.archive.org/web/20220820183122/https://www.sciencedirect.com/science/article/pii/B9780128126288500134 |url-status=live }}</ref> Pollen may be transferred through [[pollinator|pollen vectors]] or abiotic carriers such as wind. Fertilization begins when the pollen is brought to a female gamete through the pollen tube. Allogamy is also known as cross fertilization, in contrast to autogamy or geitonogamy which are methods of self-fertilization.
