Sporophyte of a moss
Web14 Aug 2013 · The lifecycle of moss alternates between the haploid gametophyte stage and the diploid sporophyte stage. A single haploid Physcomitrella patens spore gives rise a gametophore (central image). Fertilization of gametes on the gametophore apex produces a structure called a sporophyte (capsule on top of gametophore in central image). Web6 Dec 2024 · Moss gametophytes (plant-like creatures that live at the top of the moss) are the sporophytes (spore-producing plants). It is made up of a (slender stalk) and a terminal capsule (sporangium). Moss are thought to be a living organism. Moss sporocytes develop in two stages: dependent and diploid.

Due to the rapid growth of the sporogonium, the upper portion of the archegonium-neck becomes torn off, so that it is carried off in the form of a cap, ultimately forming a very large hood …
Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte. Because this embryo-nurturing feature of the life cycle is comm…
