In case of haplontic life cycle, the haploid stage is multicellular but the diploid stage is single celled. Gametophyte: The gametophyte generation is the predominant and most conspicuous phase of juniper haircap moss's life cycle. Hair cap moss, Polytrichum spp, is one of the easiest varieties of moss to grow. Moreover, in Marchantia asexual reproduction occurs by means of fragmentation of the thallus or via gemmae produced from cells of gemma cups. (E) Polytrichum piliferum , dry ventral surface of epiphragm with morphology intermediate between sacculi and annulus. Internal Structure 4.

ČeÅ¡tina: kreslený životní cyklus ploníku A moss begins its life cycle when haploid spores are released from a sporophyte capsule and begin to germinate. Diploid 2n cells arising from the zygote continue to divide to form a small sporophyte 2n. In the majority of mosses, germination is exosporic, i.e., the spore wall is ruptured by the expanding spore protoplast after its release from the capsule and prior to any cell division. ...

The life cycle of bryophytes is characterized by distinct alternation of generations in which the gametophyte is the dominant stage of the life cycle. [citation needed]. The life cycle is example of triphasic alternation of generation. Diploid phase (2n) or the sporophytic stage - gametic union results into the formation of zygote which develops into sporophyte. The Twelve Stages of the Human Life Cycle. Life cycle of Marchantia Thalli, gametophytes and gemmae The haploid thalli (single thallus) are dioecious: they produce either (female) archegoniophores or male antheridiophores. The spores then grow out into new gametophytes again, thus completing the moss life cycle. Moss Life Cycle. However, in some mosses, e.g., the character life cycle bleach gotei.
