Quick Summary

A sporangiophore is a biological structure that bears sporangia. Sporangia are sacs that produce spores, which are reproductive cells. In some fungi, spores are produced within sporangia, and these spores can be either motile (zoospores) or non-motile (aplanospores). In more advanced fungi, spores are typically formed on specialized hyphae called conidiophores, rather than in sporangia. The term "zoosporangiophore" specifically refers to a sporangiophore that bears zoosporangia. This structure is part of the reproductive process in various organisms, including fungi and some plants like bryophytes, where spores develop within sporangia.123456

…of the strobilus are called sporangiophores; each consists of a stalk bearing a flattened disk at its apex, on the lower edge of which is a ring of 5 to 10 sporangia, each one opening and shedding spores by a longitudinal slit on its inner side. The Carboniferous treelike horsetails…

…the strobilus are often called sporangiophores and have been considered to be both stem branches and of leafy origin; in the latter case they are called sporophylls. Each sporangiophore bears a number of fingerlike sporangia, which produce large numbers of thin-walled green spores. The outermost wall layer of the spore…
