- In an angiosperm life cycle, sexual reproduction includes: meiosis within the male gametophyte to produce sperm. meiosis within the female gametophyte to produce eggs. meiosis within the ovary to produce megaspores. fertilization leading to development of microspores. fertilization leading to development of megaspores.Figure 23.28 Which of the following statements about the Laminaria life cycle is false? In zoospores form in the sporangia. The sporophyte is the 2n plant. The gametophyte is diploid. Both the gametophyte and sporophyte stages are multicellular.Figure 25.24 Which of the following statements about the fern life cycle is false? Sporangia produce haploid spores. The sporophyte grows from a gametophyte The sporophyte is diploid and the gametophyte is haploid. Sporangia form on the underside of the gametophyte.
