- Self-pollination is a form of pollination in which pollen from one plant arrives at the stigma or ovule of the same plant12. It is an example of autogamy in flowering plants2. In self-pollination, the sperm in the pollen from the stamen fertilizes the egg cell present in the same plant2. This process can occur either completely autogamously or geitonogamously2.Learn more:✕This summary was generated using AI based on multiple online sources.

Wikipedia text under CC-BY-SA license Autogamy
Paramecium aurelia is the most commonly studied protozoan for autogamy. Similar to other unicellular organisms, Paramecium aurelia typically reproduce asexually via binary fission or sexually via cross-fertilization. However, studies have shown that when put under nutritional stress, Paramecium aurelia will undergo meiosis and subsequent fusion of gametic-like nuclei. This process, defined as hemixis, a chromosomal rearrangement process, takes place in a num…
