What is correct

Options

A. Protonema of moss and prothallus of Dryopteris are sporophytic
B. Protonema of moss and prothallus of Dryopteris are gametophytic
C. Moss protonema is sporophytic, Pteris prothallus is gametophytic but plant body of Pteris and Funaria are gametophytic
D. Plant body of moss is gametophytic while that of Dryopteris is both gametophytic and sporophytic

Answer

B

Explanation

Moss spores germinate to form on algae like filamentous structure called the protonema. It represents the juvenile gametophyte.
Prothallus produces only gametes (archegonia and antheridia). Prothallus never produces spores because prothallus is a gametophyte stage.
