Mosses are able to absorb a substantial amount of water and have historically been used for insulation, water absorption, and a source of peat. Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. The fertilized zygote will then develop into the diploid sporophyte. There are some robust mosses that are not in the Polytrichales. Spores have chlorophyll when released from the sporangium. The mosses in the families Dawsoniaceae and Polytrichaceae provide striking exceptions to the general rule stated at the beginning of the previous paragraph.

Variable-leaved Crestwort (Lophocolea heterophylla) is a leafy liverwort that develops a carpet of leafy shoots. However, the sporophyte generation gives them their name. survival. Wherever they are in the world, bryophytes are integral to ecosystem health. Plant from an isolated segment of a shoot break down exposed substrata, releasing nutrients for the sperm to plant! Note that in the revised classification, while the Buxbaumiaceae and Diphysciaceae are placed within the class Bryopsida, they are placed in different sub-classes. Moss grows in any location that has high moisture and low sunlight levels, such as ponds, rivers, steams or shady areas of the garden. Most of the proposed changes are the level of order or below in the class Bryopsida. In many such genera the leaves are thickened along their long central axes. Mosses are one of the most common and well-known types of bryophytes. Peristome teeth nematodontous. Within the class Polytrichopsida the members of the class Polytrichales generally have very robust gametophytes that are readily noticed.

The lifecycle is shown below. As noted above the gametophytes of the members of the Polytrichales are generally quite robust. A number of bryologists maintain that the Takakiopsida and Sphagnopsida are so unlike any other mosses that those two classes should in fact constitute separate phyla. There are a few genera (such as Leucobryum and Sphagnum) where the leaves are several cells thick. As the stems grow, the older leaves (lower down on the stem) die, leaving a living green layer atop a mass of brown, dead material. short plants resembling moss (incl.

The thallus looks like a thin dark green disk, and the sporophyte is a lighter green stalk. One such plant category is moss. The identification and delimitation of bryophyte species are complicated tasks because they are very small plants with limited, and often variable, morphological characters. Branches develop from surface cells in the originating stem and in most mosses branches are simple, single outgrowths from the originating stems. The accompanying diagram shows a cross section of a leaf of the species Aloina rigida. Instead of growing in cushions, you can also get simple-stemmed species where the plants grow separately from each other.
