Moss gametophyte has two stages of development. The first stage is protonema in which spore gives rise to thread of cells. the second stage is leafy stage which develops from secondary protonema.
It is a small leafy structure consisting of rhizoid, leaves and stem. It bears the sex organs antheridia and archegonia.
