antheridium




The male sex organ of fungi and various primitive plants. As well as fungi, antheridia are found in algae, bryophytes (liverworts and mosses), pteridophytes (club mosses, ferns, and horsetails), and cycads. They produce male gametes (sex cells) called antherozoids. These move independently in a film of water to the female gametes to achieve fertilization.
