Life cycle of a typical moss (Polytrichum commune) The moss life-cycle starts with a haploid spore that germinates to produce a protonema (pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat and thallus-like). Massed moss protonemata typically look like a thin green felt, and may grow on damp soil, tree bark ...
A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses. When a moss first grows from a spore, it starts as a germ tube, which lengthens and branches into a filamentous complex known as a protonema, from which a leafy ...
Prothallus of the tree fern Dicksonia antarctica (note new moss plants for scale) Spore-bearing plants, like all plants, go through a life-cycle of alternation of generations. The fully grown sporophyte, what is commonly referred to as the fern, produces genetically unique spores in the sori by meiosis.
The 'alternation of generations' in the life cycle is thus between a diploid (2n) generation of multicellular sporophytes and a haploid (n) generation of multicellular gametophytes.

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
Cyathophorum bulbosum, commonly known as quill moss or the false fern moss, is found in the eastern states of Australia (QLD, NSW, VIC, TAS and south-eastern SA) as well as Papua New Guinea, New Zealand, Auckland Islands, Chatham Island, Lord Howe Island and possibly Norfolk Island and New Ireland.
Pohádky z mechu a kapradí (English: The Tales of Moss and Fern) is a Czechoslovakian animated children's television series produced from 1968 to 1979. The series focuses on the adventures of two forest gnomes named Křemílek and Vochomůrka, who often dealing with certain problems.
The life cycle of a typical fern proceeds as follows: A diploid sporophyte phase produces haploid spores by meiosis (a process of cell division which reduces the number of chromosomes by a half). A spore grows into a free-living haploid gametophyte by mitosis (a process of cell division which maintains the number of chromosomes).
