#reproduction

• Axogamy — A rare morphological term used to describe a specific type of reproduction, gametic fusion, or structural organization of reproductive organs that develop exclusively along the central or main axis of a plant organism. This biological phenomenon ensures a perfect geometric alignment of reproductive structures, favoring a delicate distribution of nutrients and optimizing the chances of internal fertilization under specific ecological conditions.
• Azygospore — A zygospore formed atypically through parthenogenesis from a single gametangium, without the prior fusion of two distinct sexual reproductive cells; a plant structure or organism characterized by producing such unpaired spores.
• Azygospore — A thick-walled spore formed atypically from a single unfertilized gametangium, without the prior fusion of homologous gametangia; it represents a zygospore resulting from parthenogenesis in certain lower fungi and algae, serving as a resistance form under unfavorable environmental conditions.
