GeneralClass 12AllAnswered 27 Mar 2026
Answer
Sexual reproduction in mosses follows this sequence:
- Antheridia release biflagellated antherozoids into water
- Antherozoids swim chemotactically toward archegonia
- Fertilization occurs when an antherozoid fuses with the egg cell
- The resulting zygote develops into a multicellular sporophyte consisting of:
- Foot (absorbs nutrients from gametophyte)
- Seta (stalk)
- Capsule (produces spores via meiosis)
- Haploid spores disperse and germinate into protonema, which develops into the gametophyte
