Within the gametophyte, sperm is produced within a structure called an antheridium. The egg is produced within a similar structure called an archegonium. When water is present, sperm use their flagella to swim to an egg and fertilize it. The fertilized egg remains attached to the prothallus.

These spores are produced asexually through meiosis so their genetic material is identical to that of their parent fern. When the environmental conditions are met, the spores germinate and grow into a tiny plant called a gametophyte.
