Are Bryophytes Monoecious or Dioecious?

All bryophytes are homosporous and monoecious but Marchantia is an exception as it is dioecious. The terms monoecious and dioecious in homosporous plants refers to the gametophytes. A monoecious moss species has archegonia and antheridia on the same gametophyte.

Are mosses monoecious or dioecious?

Mosses can be either dioicous (compare dioecious in seed plants) or monoicous (compare monoecious). In dioicous mosses, male and female sex organs are borne on different gametophyte plants. In monoicous (also called autoicous) mosses, both are borne on the same plant.

Are Pteridophytes monoecious or dioecious?

The homosporous pteridophytes form monoecious prothallus whereas the heterosporous pteridophytes form the dioecious prothallus. The antheridium gives rise to numerous antherozoids which are ciliated.
