The structure that holds antheridia and archegonia in ferns is called the gametophyte. It is a small, heart-shaped structure that develops on the underside of the fern frond. Antheridia produce sperm cells, while archegonia produce egg cells for sexual reproduction in ferns.
Moss egg cells are produced by the female reproductive organs called archegonia in moss plants. The archegonia are responsible for producing and releasing the egg cells, which are then fertilized by sperm cells to form a zygote.
Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.
Moss egg cells, also known as archegonia, are produced in the reproductive structures called gametangia, which are located at the tips of the gametophyte plant body. These gametangia develop on the female moss plants, and each gametangium contains an egg cell.
Female gametes in nonvascular plants are typically produced in structures called archegonia, which are located on the female gametophyte (the haploid stage of the plant). Archegonia contain the egg cell and are designed to receive and nurture the male gametes for fertilization to occur.
Archegonia
Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.

Having antheridia and archegonia on the underside of the prothallus protects them from desiccation and mechanical damage, as they are closer to the substrate. This positioning also aids in the dispersal of sperm towards the eggs when water is present, as water carries the sperm to the archegonia.

In mosses, sperm cells are transported to the archegonia by water. The sperm cells swim in a thin film of water towards the archegonia, where fertilization takes place. This method allows for the sperm cells to reach the egg cells for sexual reproduction to occur.
Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.
Flowering Plants.
Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
