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: -Complete answer: Bryophyte is a non-flowering plant so there is no flower to contain ovule but bryophyte have a flask-shaped haploid female organ called archegonium which encloses ovule. Archegonium is present in the gametophyte phase of bryophyte.

Detailed explanation-3: -Structure of the Archegonium It is a flask-shaped structure. It consists of a neck and a swollen base called a venter. The venter contains the egg. The neck protrudes above the surface of the gametophyte.

Detailed explanation-4: -Ans: Archegonium is the female sex organ of bryophytes, pteridophytes, and gymnosperms. This female sex organ contains the female gamete the ovum.

Detailed explanation-5: -Archegonia is the female sex organ present in the gametophyte which is produced at the leafy apex in sexual reproduction. Antheridia is the male sex organ present in the gametophyte which is also produced at the apex. These are haploid structures. This type of reproduction is found in mosses.
