Mosses are bryophytes, primitive plants believed to be among the first to develop the ability to live on land. Mosses have no vascular tubes to transfer water or nutrients, and no true stems or roots. Environmental water sources and absorption limit their size. The University of Massachusetts estimates there are 14,500 moss species growing in different habitats, all having basically the same structure.
