Heterospory: Standards & Products

Heterospory is the production of spores of two distinct sizes and sexes by the sporophytes of vascular plants (in bryophytes, spore dimorphism is referred to as anisospory). The smaller of these, the microspore, is male and the larger megaspore is female. Heterospory evolved during the Devonian period from isospory independently in several plant groups…
