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.
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 .
The costa are long, sometimes excurrent, and lack an adaxial pad of cells. They are narrow distally, with hexagonal distal laminal cells measuring 10-15 μm wide. These cells bear many papillae. The moss is autoicous, and its sporophytes are exerted. Its seta measure 0.6–1.5 cm (0.24–0.59 in). Its erect and cylindrical capsules are ...
The transition from chloronema to caulonema cells along a filament is gradual [4]. Later in the development of the plant, caulonema cells can form new branches of chloronema cell type, called secondary chloronema [3]. The protonema cells grow apically, meaning that the growth of the filament happens by the division of the cells at the tip of ...
Bryum species generally have shorter laminal cells with short, thick, and rounded stems. [3] All Bryum species exhibit narrowed cells at the margins. Bryum species can be identified through patterns of asexual reproduction , coloration features of the stem and leaf base, and the strength of the leaf border.
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). [3]
Bryology (from Greek bryon, a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes. [1]
The leaves have hyaline cells at the basal margins of the leaves, which are typically square or rectangular shaped. [11] The leaf base can be expanded or gradually tapered as it connects to the stem. [12] At the tip of the leaves, there are cells with very thick cell walls. [13] At maturity, the sporangia can be ribbed or unribbed. [4]
