Most of the genera of Marchantia are c.dioecious.
Reproduction in Marchantia occurs in both ways - asexually and sexual representation.
Marchantia is a kind of plant belonging to the group of liverworts known as Marchantiales.
Their reproductive structures are shaped like umbrellas.
The lower portions have specialized structures called rhizoids.
C.dioecious is the correct answer.
Dioecious plants house the male and female flowers on different plants. So not only does the plant have separate male/female flowers, they have male plants (with only male flowers) and female plants (with only female flowers). Hollies and asparagus are dioecious. Since only the female plants can produce the fruit, hollies must have a male plant and a female plant in close proximity. Male holly plants are often given masculine names like 'Southern Gentleman', 'Jim Dandy', or 'Blue Prince', so they are easy to recognize. In the landscape, one or two male hollies are often tucked behind the female hollies to ensure pollination and fruit set and to hide the male plants that don't produce the showy fruit.
