Within the gametangia, specialized cells called gametes are produced. There are two types of gametangia:

* Antheridia: These produce sperm (male gametes).

* Archegonia: These produce eggs (female gametes).

Bryophytes are non-vascular plants, meaning they lack specialized tissues for transporting water and nutrients. As a result, they rely on water for fertilization. The sperm must swim to the egg, which is located inside the archegonium.
