Treating the common cold during pregnancy.

Gametophytes. The gametophyte is the dominant phase in the life cycle of moss plants. This is the form of the plant most people are familiar with since it is often seen carpeting trees, rocks, and parts of the forest floor. Photosynthesis takes place in the gametophyte phase.
They are one of the oldest living vascular plants. The club mosses are part of the family Lycopodiaceae and the Phylum Lycophyta. The Lycophytes were once a large group of land plants that existed during the Carboniferous Period. These lycophytes grew to be as tall as 100 feet. About 250 million years ago though, most of the species had died out. The club mosses that we know of today are evergreen plants with needle-like leaves. Like other vascular plants, club mosses have true roots, leaves and stems. This allows for the plant to absorb water and minerals. The club mosses also have an underground horizontal stem called a rhizome.
