Detailed explanation-1: -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.

Detailed explanation-2: -Each antheridium produces numerous sperm. The eggs are produced in tiny, typically somewhat flask-like structures called archegonia. Each archegonium holds one egg (in a swollen section called the venter) and the sperm enter through the channel in the narrower, tubular section (or neck).

Detailed explanation-3: -The female structure for producing eggs is known as the archegonium, and the male structure for producing sperm is known as the antheridium. Antheridia are tiny, typically stalked, club-shaped or spherical structures. Archegonia are bottle-like containers, their wall just one cell thick.

Detailed explanation-4: -This is called the venter. The venter is the location where the female gamete or egg will be produced and developed. Leading up from the venter is the neck of the archegonium.

Detailed explanation-5: -Archegonium Function In non-flowering plants, the archegonium produces female gametes. Gametes are haploid germ cells (cells that become sperm or egg cells). When a gamete is in contact with another gamete of the opposite sex, this will form a zygote.
