spermatangia
Quick Summary
A spermatangium is a multicellular antheridium, which is a male reproductive organ found in some algae. In plants, male gametes (sperm) are produced in structures called antheridia. The term "spermatial" relates to bearing or being a spermatium. This is distinct from spermatogenesis, which is the process of sperm cell development in male reproductive organs. In certain plants, specialized structures called sporangia produce spore mother cells that develop into spores, which can then give rise to gametophytes.12345

algaeReproduction and life histories…the male gametophyte produces special spermatangial branches that bear structures, called spermatangia, which contain spermatia, the male gametes. The female gametophyte produces special carpogonial branches that bear carpogonia, the female gametes. Fertilization occurs when a male spermatium, carried by water currents, collides with the extended portion of a female carpogonium…
