Detailed explanation-1: -Depending on species or their stage of development, they may resemble small umbrellas, palm trees, or capped mushrooms. These female reproductive structures are called archegonia. The male reproductive structures may resemble a wart or they may have a tall, stalked appearance. These are called antheridia.

Detailed explanation-2: -In many species of liverworts, such as Marchantia, the one you will most likely see in lab, the antheridia and archegonia are not on top of the plant, but hanging down from the underside of odd little structures that look like tiny umbrellas.

Detailed explanation-3: -As in all of the early diverging land plant lineages, liverworts have antheridia and archegonia that develop on the gametophyte.

Detailed explanation-4: -The male reproductive organ of Marchantia is the antheridia. The female reproductive organ of Marchantia is archegonia. Antheridiophore is a stalk on which the antheridia are borne. Archegoniophore is the stalk on which the archegonia are borne.
