WebThe gametophyte produces sex cells (sperm and eggs) in specialized structures called archegonia and antheridia, respectively. Fertilization occurs when a sperm cell swims through water to reach an egg inside the archegonium, forming a diploid zygote. The zygote develops into a new sporophyte, completing the cycle.

Websperm are released from the antheridium and swim through a thin film of water to a nearby archegonium to fertilize the egg. Since the antheridium and archegonium are on the same prothallus the fern has several strategies to prevent self-fertilization. These strategies will be discussed later in this slow down and speed up video
