WebIn the living Lycopodiophyta species: spike mosses (Selaginellaceae) and quillworts (Isoetaceae) are heterosporous, while club mosses (Lycopodiaceae) are homosporous. Many club moss and spike moss species produce spores in specialized structures called strobili, which are a group of modified non-photosynthetic sporophylls (spore bearing leafs). WebMosses are heterosporous, which means they make two distinct types of spores; these develop into male and female gametophytes. Male gametophytes develop reproductive structures called antheridia (singular, …

Heterospory - Wikipedia

WebHeterosporous plants, such as seed plants, ... In Common Smoothcap moss (Atrichum undulatum), the vibration of sporophyte has been shown to be an important mechanism for spore release. In the case of spore-shedding vascular plants such as ferns, wind distribution of very light spores provides great capacity for dispersal. Also, spores are less ... Heterosporous spores can respond independently to selection by ecological conditions in order to strengthen male and female reproductive function. Heterospory evolved from homospory many times, but the species in which it first appeared are now extinct. See more Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. The smaller of these, the microspore, is male and the larger megaspore is female. Heterospory evolved during the See more Heterospory evolved due to natural selection that favoured an increase in propagule size compared with the smaller spores of … See more Heterospory was a key event in the evolution of both fossil and surviving plants. The retention of megaspores and the dispersal of microspores allow for both dispersal and establishment reproductive strategies. This adaptive ability of … See more Microspores are haploid spores that in endosporic species contain the male gametophyte, which is carried to the megaspores by wind, water currents or animal vectors. Microspores are not flagellated, and are therefore not capable of active movement. … See more WebJul 31, 2011 · Mosses are heterosporous because they produce two distinct gametophytes that develop into either archegonium or antheridium.
