Reproduction of ferns

Fern spores  germinate and can give life to different gametophytes (male and female gametophytes). Often gametophytes generate a single type of gametophyte, a few centimetres in size, that lives in the presence of water. Gametophytes are often heart-shaped, and have only one layer of cells containing chlorophyll. The archegonium and antheridium are present in separate areas, and these wrap around the gametes. The antheridium contain a large number of multi-flagellate sperms, and if there is sufficient humidity, they come out and by chemotropism, they move towards the archegonium.
