The sporophyte? When egg and sperm merge, they form a diploid zygote which grows into a diploid sporophyte. Are members of the gametophyte generation in mosses haploid or diploid? Tracheophyte Question 2 In angiosperms this is the dominant stage: haploid gametophyte diploid gametophyte diploid sporophyte haploid sporophyte . Gamete and gametophyte are two haploid structures of sexual phase of the living cycles of plants and algae. Gametophytes contain sex organs that involve the production of gametes. Questions 01. Stock Plant with a root system onto which a twig or bud from another plant (called a scion) is grafted. The spore develops into a gametophyte which is haploid in nature. The gametophyte consisting of reproductive organs undergo mitosis to form haploid gametes. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte. Explain the difference between the sporophyte and gametophyte generation in plants. Q3. Would you desci be the gametophyte or sporophyte as the dominant stage in the life cycle? Would you describe the sporophyte as dependent or independent? Unlike more advanced plants, mosses have a dominant haploid life stage. Sporophytes produce haploid spores, containing genetic information from both haploid gametophyte parents. Q2. The Haploid Stage. In plants, alternation of generations exists, where the members have haploid and diploid phases. Sporangium present in diploid sporophytes undergo meiosis to form haploid spores. State which generation is haploid and which is diploid; Name the process that makes spores and state if spores are haploid or diploid; Name the process that creates sperm and egg from spores and state if sperm and egg are haploid or diploid The elateres are formed by expansion of diploid sporangium cells. Would you say the moss requires water for fertilization? The mature haploid gametophyte then produces gametes by mitosis. We human beings have 23 chromosomes on a single set. These gametes fertilize to produce a haploid zygote which matures into a mature sporophyte. We are diploid organisms and thus all the cells of our body carries two set of chromosomes (thus 23*2=46). When the cap of the sporangium opens these haploid spores are spread and they can grow into a new gametophyte. Gametophyte – haploid stage in the life cycle of plants that produces haploid... of generations involving a diploid sporophyte and a haploid gametophyte. Get more help … As far as dominance is concerned, in liverworts and mosses, the gametophyte stage is the larger and familiar form of the plant, whereas the sporophyte stage is smaller and is found growing on the gametophyte stage. Q5. In animal cells, haploid cells (gametes) are only produced by meiosis and only diploid cells undergo mitosis. After meiosis, haploid spores are formed inside the sporangium. Read on to explore more differences between the two. Haploid refers to 1 set of chromosome, diploid refers to 2 set of chromosomes, triploid means 3 set of chromosomes. In a nutshell, haploid gametophytes produce haploid gametes, which can be sperm or eggs. On the other hand, the gametes are the sex cells or the germ cells, which undergo fertilization to form a zygote, which is diploid. This process differs from what is seen in animal organisms. This diploid sporophyte is entirely dependent of the haploid gametophyte that surrounds it. Sporophyte A diploid plant or plant structure that produces haploid spores through meiosis. Stigma The top part of the pistil, where pollen grains are received. They don't represent the numbers of chromosome present on a set. Haploid cell from which a gametophyte is produced. In plants, the gametophyte phase ends with the formation of a diploid zygote by sexual reproduction. In the sporophyte phase, haploid spores are formed and in the gametophyte phase, diploid male and female gametes are formed. Q4.
