25 Μαρ 2018 · The gametophyte of ferns is a cellular monolayer structure, whose more important function is to form the gametes, responsible of sexual fusion that will lead to sporophyte generation. In most cases, as sporophyte develops, the gametophyte is about to disappear, reflecting to have a role purely involved on reproduction.

1 Ιουλ 1999 · The fern gametophyte has interested plant biologists for the past century because its structure and development is simple and amenable to investigation.
During its life cycle, a fern exists in two distinct forms: the small, sample, haploid gametophyte and the large, morphologically complex, diploid sporophyte. In ferns,
The fern Vittaria appalachiana, for example, is only known from its gametophytes (Farrar and Mickel, 1991). Each gametophyte forms vegetative buds, or gammae, that allow gametophytes to multiply and form mats in dark, moist cavities and rock shelters in the Appalachian Mountains.
Ferns (monilophytes) and lycophytes are unique among land plants in having two independent life stages: the gametophyte generation, which is generally small, cordiform, and short-lived, senescing after fertilization, and the sporophyte generation, which is considered the dominant, long-lived portion of the life cycle produced following fertiliza...
1 Ιουλ 2022 · Fern gametophytes develop meristems that renew themselves through continuous cell division and produce new cells that differentiate into a photosynthetic prothallus or into cells that form the...
