II) Meiosis occurs in sporophytes to produce spores. C) The gametophyte is within the flower in angiosperms. Mitosis occurs in gametophytes to produce gametes. Answer: Reproductive spores are generally the result of cell division, most commonly meiosis (e.g. Sporophyte is defined as the plant having two sets of chromosomes (diploid), which can produce haploid spores by means of meiosis. Megaspores grow into female gametophytes, and microspores grow into male gametophytes. I, II, and III. Who are the experts? II. The zygote undergoes mitosis and develops into the diploid sporophyte. E) Mitosis occurs in gametophytes to produce gametes, meiosis occurs in sporophytes to produce spores, and the gametophyte is within the flower in angiosperms. The zygote develops into the diploid sporophyte, which extends from the gametophyte and produces haploid spores through meiosis. Once the spores germinate, they produce new gametophyte plants and the cycle continues. In which part of the flower meiosis takes place and why? A gametophyte is created when the sporophyte generation produces spores. After the spores are released they germinate, divide by mitosis and grow into simple heartshaped gametophytes. C) The gametophyte is within the flower in angiosperms. Meiosis in a mature related to plants. Meiosis occurs in the primordial germ cells, cells specified for sexual . Four haploid girl cells are delivered toward the end, dissimilar to two diploid little girl cells in mitosis. The sporophyte dies after releasing its spores, but maternal gametophytes usually survive the death of their diploid offspring and may continue to reproduce both sexually and asexually (see figure 1 b ). In mammals, the gametes are the direct products of meiosis (no division of the haploid cells occurs). These spores then form gametophyte, thus exhibiting alternation of generation. What is the difference between sporophyte and gametophyte? Meiosis occurs in the sporangium of a sporophyte and results in haploid spores. This type of life cycle is called a haplodiplontic life cycle ( Figure 20.1 ). Spores are made by meiosis or cell division that reduces the number of chromosomes by half. in plant sporophytes). They also allowed bryophytes to produce many more spores than their algal ancestors. c. The gametophyte is the dominant generation in flowering plants. The meiospore grows to develop into the gametophyte. In flowering plants, meiosis occurs in megaspore mother cells (megasporocytes) within the ovules of ovaries, and in microspore mother cells (microsporocytes) within the anthers of stamens. The plants are sporophytes and reproduce by spores which result from meiosis. How do you know if something is a sporophyte? Experts are tested by Chegg as specialists in their subject area. Meiosis occurs in sporophytes to produce spore Identify three diseases of the respiratory . How Does Mitosis Help A Plant Grow? Where does the meiosis occur in a plant? 14 Where does meiosis happen in females? Meiosis. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms. III) The gametophyte is within the flower in angiosperms. . Where does meiosis occur in a flowering plant quizlet? This cycle is known as alternation of generations or alternation of phases. 15 Do sperm cells undergo meiosis? B) Meiosis occurs in sporophytes to produce spores. These spores develop into haploid gametophytes, which in turn form gametes through mitotic division. Meiosis occurs within sporangia, located on the underside of the sporophyte leaf. Haploid spores germinate into haploid gamete-producing bodies in gametophytes. These gametes fertilised to produce a haploid zygote which matures right into a mature sporophyte. Meiosis occurs in ~ sporangia, located on the underside that the sporophyte leaf . Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms. Since spores are formed in this generation, the name given to this phase is sporophyte. Meiosis occurs in the primordial germ cells, cells specified for sexual . Cell division in plants is concentrated in meristems , although plants are unusual in that mature cells can return to cell division under the right . Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. gametes by mitosis. This alternation of generations is a survival strategy in which a plant or algae alternates between different reproductive techniques. B. II) Meiosis occurs in sporophytes to produce spores. The job of a sporophyte is to produce spores. Take care not to confuse the sporophytes produces haploid spores, alternation of generations in plants with the The gametophyte produces reproductive cells that can . The process by which Apospory occurs in ferns is detailed below. Mitosis occurs in gametophytes to produce gametes. Sporophytes produce. The sporophyte produces haploid spores by meiosis. Relative to the familiar sporophytes, the fern gametophytes are small and inconspicuous. . Answer (1 of 4): This is my answer to a previous question. and females would produce haploid spores by meiosis. These spores would give rise to multicellular male and female haploid stages—a major change from the single celled haploid stages (sperm and eggs) that we actually have. Are Sporophytes haploid? Step 1: The sporophytes, a diploid multicellular organism that either produced haploid spores or diploid zygote, which are produced by the fern.. Apospory in Ferns. The basic function of the sporophyte is to create spores - that much is known already. Instead of using meiosis to produce sex cells, they use meiosis to produce spores - which then undergo mitosis to grow into whole new haploid organisms, a.k.a. spores: Which of the following is the correct sequence during alternation of generations in a flowering plant? sporophyte-meiosis-gametophyte-gametes-fertilization-diploid zygote : Which of the following is true in plants? Meiosis occurs in pollen mother cells. gametophytes! Haploid plants are termed gametophytes; diploid plants are termed sporophytes. III) The gametophyte is within the flower in angiosperms. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote. Spores will then undergo mitosis to grow into a multicellular haploid gametophyte. The sporophyte stage of bryophytes is diploid, with two versions of each chromosome in its DNA, while the gametophyte is haploid with only one. The gametophyte is within the flower in angiosperms. A spore is a tiny structure that leads to a new plant after its germination. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms. I think it also answers this question. Sporophytes are diploid plants that use meiosis to produce spores. What about ferns? Fertilized eggs in gametophytes form sporophytes at the site of fertilization. The sporophytes of bryophytes can give rise to one spore at a time, but the gametophytes can form many sporophytes at a time. In fungi and fungus-like organisms, [clarification needed] spores are often classified by the structure in which meiosis and spore production occurs. a. by gametophytes through mitosis b. by sporophytes through meiosis c. by gametophytes through meiosis d. by sporophytes through mitosis 2 See answers . Where does meiosis occur in a flowering plant quizlet? Spores in turn undergo mitotic cell divisions to produce the multicellular, haploid gametophyte. Where does meiosis occur in a flowering plant? Step 2: These sporophytes then undergo gene activation, form an embryo sac, and result in the formation of gametophytes after maturation. These spores can divide and produce male or female gametophytes. Completing one life cycle, a spore develops by mitosis into a gametophyte. III) The gametophyte is within the flower in angiosperms. The spores, in turn, produce the gametophytes that give rise to the male and female gametes through the process of meiosis. Meiosis occurs in the sporangium of a sporophyte and results in haploid spores. The gametophyte inclusive of reproductive organs goes through mitosis to form haploid gametes. The sporophyte phase is dominant in all plants except mosses. Why meiosis is essential at the time of Sporogenesis in angiosperms Class 12? zygote produces a multicellular diploid sporophyte does not occur in the charophytes, the algae most closely ("spore-producing plant"). 1 See answer Advertisement Advertisement Kittykat4555 is waiting for your help. Meiosis is the process of cells splitting into four haploid cells, thus reducing the chromosome number by half in each cell. By using mitosis to multiply the number of diploid cells that can divide by Diploid (2n) generation: all cells of plant contain a double set of chromosomes. (sperms and eggs), whereas meiosis in plants produce spores. The sporophyte generation is short-lived. These spores are haploid cells that grow into haploid gametophytes. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores. Show transcribed image text Expert Answer. sporophyte-meiosis-gametophyte-gametes-fertilization-diploid zygote : Which of the following is true in plants? Spores . Meiosis occurs in pollen mother cells. he pathway of a breath of air from the nose to the alveoli. IV. A) Mitosis occurs in gametophytes to produce gametes. e. Male gametophytes and female gametophytes have the same structure. In the sporophyte phase, meiosis occur in the sporangium (plural: sporangia). The former is responsible for forming haploid egg and sperms which further forms a diploid sporophyte that eventually produces haploid spores. Cell division in plants is concentrated in meristems , although plants are unusual in that mature cells can return to cell division under the right . gametes by meiosis. Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. The products of meiosis in plants are always which of the following? Meiosis occurs in sporophytes to produce spore Meiosis takes place in a specialized structure on the sporophyte called sporangium to produce spores. Where does cell division in plants occur? B) Meiosis occurs in sporophytes to produce spores. Haploid male and female gametophytes produce gametes by mitosis. The products of meiosis in plants are always which of the following? Meiosis 1 Stages. In plants, meiosis produces haploid nuclei that become spores. A) only I B) only II C) only III D) only I and II E) I, II, and III Sporophytic phase is universally present in all types of true plants (herbs, shrubs, trees), some algal species and aquatic fungi. Meiosis occurs in sporophytes to produce spores. How are moss spores produced? Meiosis occurs in sporophytes to produce spores. general-biology. Sporic meiosis is needed to complete the sexual life cycle of the organisms using it. The diploid sporophytes appear only occasionally and remain attached to and nutritionally dependent on the . The gametophyte is within the flower in angiosperms. 13 Where does mitosis and meiosis occur in the human body? What do Sporophytes produce? In ferns, these cells are the spores. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms. As its name suggests, the function of the sporophyte stage is to generate the spores through meiosis. asked Aug 26, 2015 in Biology & Microbiology by Pikachu. 18 Does meiosis occur in? Meiosis occurs in two places in the flower: in the anther sacs of stamens and in the ovules found within the ovary (the basal part of the carpel). Spores are haploid reproductive cells. Meiosis takes place within the sporangium to produce large numbers of haploid spores that are (in most cases) aerially dispersed. The diploid sporophyte produces haploid spores by meiosis, the same process that produces eggs and sperm in animals and flowering plants. The value of these first sporophytes must have been enormous because they would have protected the developing spores from desiccation. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms.
