The important pari of the sporophyll is the spore is a cell that is capable of germinating or growing underfavorable conditions ami thus producing some kind i a neworganism, or we ma) saj a new plant. You arc always to thinkof a spore as having this power. In case of the spores under consideration very rudimentary plants are produced that con-sisl of only a few cells. These minute plants are very A V
