Content: Now, the germination of spore depends on favorable conditions. A spore could germinate if it lands in a suitable damp location followed by growth into a thread like structure. This thread like structure, now, branches to form rhizoids and buds and that grow upright. Each bud has the capability to develop into a new gametophyte plant consisting of a leafy axis. The major portion of the life cycle of moss is spent in the haploid state. The leafy gametophyte is photosynthetic. However, the smaller sporophyte is not photosynthetic and it is not able to produce energy on its own. Hence, it is nutritionally dependent on the gametophytes. Water is an important component required to carry the sperm to the egg. Abundance of Mosses
Mosses are the most abundant plants in the Arctic and the Antarctic area.
