Do ferns do meiosis?
Unlike some other non-flowering vascular plants, ferns produce one type of spore (homosporous) via meiosis in the sac-like sporangia. Within each sporangium, the diploid spores (spore mother cells or sporocytes) undergo meiosis.
Where does meiosis occur in most plants?
Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants. In angiosperms, meiosis takes place in sporogenous cells that develop de novo from somatic cells in anthers or ovules.
What type of spores are produced in fern plant?
Some lycophytes and ferns are heterosporous (two kinds of spores are produced). These plants produce microspores and megaspores, which give rise to gametophytes that are functionally male or female, respectively.
In what structure does meiosis occur in the bryophytes?
Meiosis takes place in the tiny sporophyte stage of bryophytes, which are attached to and dependent on the much larger gametophyte stage. The sporophytes create spores by meiosis in the sporangium, which are dispersed by wind and water to form new gametophytes.
