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.
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.
In hornworts, the meristem starts at the base where the foot ends, and the division of cells pushes the sporophyte body upwards. In mosses, the meristem is located between the capsule and the top of the stalk (seta), and produces cells downward, elongating the stalk and elevating the capsule.
Bryum argenteum, the silvergreen bryum moss or silvery thread moss, [1] is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope.
A spore develops into a filamentous structure called protonema, composed of two types of cells – chloronema with large and numerous chloroplasts and caulonema with very fast growth. Protonema filaments grow exclusively by tip growth of their apical cells and can originate side branches from subapical cells. Some side-branch initial cells can ...
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 ...
Moss plant Funaria grows in dense patches or cushions in moist shady and cool places on rocks, walls or crevices during the rainy seasons. It has a height of 3–5 cm, a radial symmetry with a differentiation of an axis or stem, leaves or phylloids are multicellular colorless branched rhizoids with oblique septa.
Funaria hygrometrica, the bonfire moss [1] or common cord-moss, [1] is a type of water moss which grows on shady, moist soil. It can also be found on moist walls and the crevices of rocks and places where recent fires have taken place.
