Welcome to ohioplants.org, your on-line companion to Ohio Plants, EEOB 2210. Look here for examples of the concepts we're covering in lecture and lab. Moss Life Cycle
A moss SPORE germinates and develops into a green mass of thin threads called the PROTONEMA. The protonema, a phase in the gametophyte stage of the life cycle, resembles a filamentous green alga. Note: The moss life cycle figures here are redrawn with slight modification from A Laboratory Manual for Botany by Margaret Balbach and Lawrence Bliss (2002). Below, see the protonema of a quick-growing, short-lived little cushion moss (acrocarp) of open sites, Physcomitrium pyriforme, with the leafy phase of the gametophyte just starting to spring forth from it.

A moss protonema is the threadlike early form of the gametophyte stage of the life cycle. The moss GAMETOPHYTE is the dominant stage in its life cycle: persistent, photosynthetic, and assimilating resources from the environment.
