Gametophyte plant body
WebExternal structure of gametophyte. Plant body is gametophytic and consists of two stages: juvenile and adult. The juvenile stage is represented by "primary protonema" (thread-like structures formed directly by spore germination). The adult stage is represented by leafy gametophore which is differentiated into rhizoids, axis and leaves. WebPlant body is clearly differentiated into root, stem and leaves. 3. ... Sporophyte is the dominant generation, gametophyte highly reduced. iii. Plant body is differentiated into root, Stem and leaves iv. They bear flower in which male and female gametes develop. v. Vascular bundle (conducting tissues) shows higher degree of development. ...

WebPlants show alternation of generation between a gametophytic and a sporophytic body. The gametophytic body can be either male or female. These are haploid structures which produce gametes. The gametes fuse to form a zygote and give rise to a diploid sporophytic body.

WebIn plants, both haploid and diploid cells can divide by mitosis. This ability leads to the formation of different plant bodies - haploid and diploid. The haploid plant body produces gametes by mitosis. This plant body represents a gametophyte. Following fertilisation the zygote also divides by mitosis to produce a diploid sporophytic plant body. city of birmingham waterWebGametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis.
