- In the moss Polytrichum commune, the haploidchromosome number is 7. A haploid male gametefuses with a haploid female gamete to form a diploid cell that divides and develops into the multicellular sporophyte. Cells of the sporophyte thenundergo meiosis to produce haploid cells calledspores. What is the probability that an individualspore will contain a set of chromosomes all ofwhich came from the male gamete?The leafy, green moss plants that are familiar are gametophytes, haploid plants. This is very different from flowering plants and other seed plants. Does a leafy green moss plant grow from a spore or from a fertilized egg? Does the moss plant have both paternal parent and maternal parent?Which of the following lettered structures is the female gametophyte?
- In homospory, the megaspore develops into female gametophyte True or FalseWhich of the following is TRUE for animal life cycle, but not for plant life cycle? O gametes are formed by mitosis O gametes are formed by meiosis O unicellular gametes O multicellular gametophytes O spores are formed by meiosis « PrevjousFigure 24.14 Which of the following statements is true? A dikaryotic ascus that forms in the ascocarp undergoes karyogamy, meiosis, and mitosis to form eight ascospores. A diploid ascus that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A haploid zygote that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A dikaryotic ascus that forms in the ascocarp undergoes plasmogamy, meiosis, and mitosis to form eight ascospores.
- In plant life cycles, (a) the first products of meiosis are gametes (b) spores are part of the diploid sporophyte generation (c) the embryo gives rise to a zygote (d) the first stage in the diploid sporophyte generation is the zygote (e) the first stage in the haploid gametophyte generation is the prothallusor lds P e t CO ea pre SC ctu of it h lu fru 0 2 > Regular 3 WW Where does meiosis take place in mosses?

Be sure to show the cycle from one generation to the next.
- Draw a simple diagram illustrating alternation of generations in plants, including the sporophyte and gametophyte generations, spores, gametes (eggs and sperm), meiosis, and fertilization. Be sure to indicate whether each generation or kind of cell is haploid or diploid.How are gametes formedin the pteridophyte life cycle,by mitosis or meiosis? What isthe type of meiosis that occursin pteridophytes?You may have noticed that the undersides (but never the upper sides) of fern leaves have brown dots or brown streaks or brown patches. The brown dots are called (singular, ), clusters of where meiosis occurs. If a leaf carries these structures, the leaf is called a .
