Why are mosses considered plants?
Mosses. Mosses are a phylum of non-vascular plants. They produce spores for reproduction instead of seeds and don’t grow flowers, wood or true roots. Instead of roots, all species of moss have rhizoids. The mosses sit within a division of plants called the Bryophyta under the sub-division Musci.

What Is Moss?
Moss is in the division Bryophyta. As a type of Bryophyte, moss is a spore-producing nonvascular plant. Because vascular systems help plants stay rigid and grow upright, moss is typically very small and stays low to the ground. In addition, moss gets its water and nutrients by absorbing everything directly through its leaves, unlike vascular plants which have roots.

What happens to moss after it is released?
However, after the sporophyte generation has released the spores, it dies off. The spores find a place to settle, and develop into a haploid organism, the gametophyte. This is the dominant structure of moss, what you typically see if the moss is not reproducing. This can be seen in the image at the base of the sporophyte, much shorter and seemingly a different species. The gametophyte is responsible for producing gametes, which are capable of fusing together. Look at the image below, of moss reproduction.

Where are moss plants found?
The moss found in the class Andreaeobryopsida represents only a couple species. These moss species are endemic to only a few parts of Alaska and Western Canada. These moss plants have developed a unique tolerance to the climate in this region. This, plus differences in their genetics and the development of their spore capsules, led scientists to remove them from the Bryopsida and into their own unique class.
