During the gametophyte stage of bryophytes
WebApr 9, 2024 · In bryophytes, such as mosses, the haploid gametophyte is more developed than the sporophyte. During the vegetative phase of growth, plants increase in size and produce a shoot system and a root system. As they enter the reproductive phase, some of the branches start to bear flowers.

WebJun 7, 2024 · During the mature gametophyte stage, several mosses including, Sphagnum recurvum, Sphagnum cuspidatum, and Sphagnum palustre, bear large central vacuoles in thick walled sterome cells, while the internal thin-walled cells possess abundant number of small vacuoles ( Ligrone and Duckett, 1998 ). WebRegular heteromorphic alternation of generation occurs in bryophytes. The gametophyte produces haploid gametes. After fertilization the oospore gives rise to diplopod sporophyte. The sporophyte produces the spores by meiosis. The spores give rise to the gametophyte.

Hornworts The hornworts (Anthocerotophyta) belong to the broad bryophyte group that have colonized a variety of habitats on land, although they are never far from a source of moisture. The short, blue-green gametophyte is the dominant phase of the lifecycle of a hornwort. The bryophyte lifecycle consists of alternating generations between the haploid gametophyte and the diploid sporophyte.
