An archegonium (pl.: archegonia), from the Ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. …

archegonium, the female reproductive organ in ferns and mosses. An archegonium also occurs in some gymnosperms, e.g., cycads and conifers. A flask-shaped structure, it consists of a neck, with one or more layers of cells, and a swollen base—the venter—which contains the egg.

The meaning of ARCHEGONIUM is the flask-shaped female sex organ of bryophytes, lower vascular plants (such as ferns), and some gymnosperms.

Nov 18, 2019 · The main difference between antheridium and archegonium is that antheridium is the haploid structure producing male gametes in cryptogams such as ferns and bryophytes, whereas archegonium is the multicellular structure producing female gametes in both cryptogams and gymnosperms.

Mar 22, 2025 · Fern - Sporangia, Gametophytes, Alternation: The sex organs of ferns are the antheridium and the archegonium. Within the archegonial venter the zygote undergoes cell divisions to form the embryo, which usually has a development distinctive to ferns.

Jun 7, 2024 · Archegonia are the female reproductive structures found in certain groups of plants, including bryophytes (mosses and liverworts), ferns, and some gymnosperms. These structures are essential in the sexual reproduction of these plants, as …

Archegonium (sing.) or archegonia (plu.) are structures borne on the gametophytes of plants that bear ovum or female gamete. The male counterpart of an archegonium is the antheridium. Archegonia are characteristic of bryophytes and cryptograms (plants that do not produce seeds), but are usually found in some gymnosperms also.

The archegonium represents one of the key evolutionary innovations for sexual reproduction in land plants. This structure expressed on female plants provides protection and nourishment for the egg and developing embryo.
