Does meiosis occur in moss?
The most conspicuous stage of moss is the gametophyte: A haploid stage. … The zygote develops as a multicellular sporophyte, but remains dependent on the female gametophyte. Meiosis takes place in a specialized structure on the sporophyte (the sporangium), producing spores (not gametes!).
Are the spores produced by the moss sporophyte formed by meiosis or mitosis are the spores haploid or diploid?
Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a diploid zygote which develops into a new sporophyte.
Do mosses go through mitosis?
Gametophyte. The leafy green plant part of the moss that will either produce sperm or eggs. … Gametophytes produce haploid male or female gametes (or both) by a process called mitosis that we will cover in detail later.
How are moss spores produced Brainly?
Spores produced on underside of fronds in clusters of sporangia called sori. Spores undergo meiosis, are spread by wind, & germinate on moist soil to form prothallus. Prothallus begins the Gametophyte stage.
Are the spores produced by the fern sporophyte formed by meiosis or mitosis?
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.
Are moss gametes haploid or diploid are they produced by meiosis or mitosis?
The most familiar form of the moss is the “leafy” haploid form, called the gametophyte. Gametophytes are either male or female. The male gametophyte produces male gametes—sperm—inside reproductive structures called antheridia. The haploid gametophyte produces these haploid sperm by mitosis.
What process is used by the sporophyte to produce spores?
In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.
