The sporophyte is differentiated into a foot, seta and capsule. After meiosis, spores are produced within the capsule. These spores germinate to form free-living gametophytes.
Which of the following statements regarding vegetative reproduction and early life cycle stages in bryophytes are correct? S1: Vegetative propagation in mosses primarily occurs by fragmentation and budding in the secondary protonema. S2: Gemmae are green, multicellular, asexual buds, which are haploid and develop in small receptacles called gemma cups in liverworts. S3: The gemmae produced in liverworts, upon detachment, germinate to form new independent sporophytes. S4: The protonema stage, which develops directly from spores in mosses, is a haploid, creeping, green, branched, and filamentous stage. S5: Spores are produced in the capsule of the liverwort sporophyte following mitosis, and these germinate to form new free-living gametophytes.
