Massed moss protonemata typically look like a thin green felt, and may grow on damp soil, tree bark, rocks, concrete, or almost any other reasonably stable surface. This is a transitory stage in the life of a moss, but from the protonema grows the gametophore ("gamete-bearer") that is structurally differentiated into stems and leaves. A single ...
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.
The moss has adapted to grow in low light conditions by utilizing spherical cells in the protonema that act as lenses, collecting and concentrating even the faintest light. The chloroplasts absorb the useful wavelengths of the light and reflect back the remainder towards the light source, giving the moss a greenish-gold glow. [ 4 ]
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.

Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that have a cosmopolitan distribution. The genus Polytrichum has a number of closely related sporophytic characters. The scientific name is derived from the Ancient Greek words polys, meaning "many", and thrix, meaning "hair".
A temperature-controlled terrarium with plants inside. A terrarium (pl. terraria or terrariums) is a glass container containing soil and plants in an environment different from the surroundings. It is usually a sealable container that can be opened for maintenance or to access the plants inside; however, terraria can also be open to the atmosphere.
Hylocomium splendens, commonly known as glittering woodmoss, [2] splendid feather moss, [3] stairstep moss, and mountain fern moss, is a perennial clonal moss [4] with a widespread distribution in Northern Hemisphere boreal forests. It is commonly found in Europe, Russia, Alaska and Canada, where it is often the
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.
