Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack lignified water-conducting tissues, they cannot become as tall as most vascular plants. Algae, especially green algae. The algae consist of several ...
Like all moss, the haploid gametophyte is the dominant phase of the lifecycle of P. formosum. The moss gametophyte has photosynthetic leaves, a stem, and root-like rhizoids that anchor them to the substrate. [9] Polytrichastrum formosum is a medium to large robust acrocarpous moss, growing in uncrowded, unbranching tufts.
An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses (Bryophyta sensu lato).

Spanish moss (Tillandsia usneoides) is an epiphytic flowering plant that often grows upon large trees in tropical and subtropical climates. It is native to much of Mexico , Bermuda , the Bahamas , Central America , South America (as far south as northern Patagonia ), [ 4 ] the Southern United States , and West Indies .
Young sporophytes of the common moss Tortula muralis. In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes Sporophytes of moss during spring In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and ...
D. superba is the tallest self-supporting moss in the world, reaching heights of 60 cm (24 in). [4] It has analogous structures to those in vascular plants that support large size, including hydroid and leptoid cells to conduct water and photosynthate, [4] and lamellae that provide gas chambers for more efficient photosynthesis. [5]
Chloroplasts, containing thylakoids, visible in the cells of Rosulabryum capillare, a type of moss. A chloroplast (/ ˈ k l ɔːr ə ˌ p l æ s t,-p l ɑː s t /) [1] [2] is a type of organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.
