The sori and indusium superficially resemble an infestation of scale insects, and some people actually spray their ferns! Answer Save. Are The Spores Produced By The Fern Sporophyte Formed By Mitosis Or Meiosis? However, diploid generation is better adapted due to two pairs of a gene that harmful gene due to mutation may be masked and there is greater opportunity for variation whereas the haploid has one gene. The plant often reproduces vegetatively as well by producing a rhizome that develops underground and then produces a new plant. allows for the mixing of genetic material (genetic variability). Meiosis and not mitosis must be used to produce gamete. Do The Spores Belong To The Gametophyte Or The Sporophyte Generation? Plants exhibit haplodiplontic life cycle wherein the gametes (sex cells) are not a direct product of Transcript. The number of cells within an organism increases by mitosis and this is the basis of growth in multicellular organisms.

In mosses gametes are produced by _____; in ferns gametes are produced by _____. Are the archegonia and antheridia haploid or diploid? Meiosis is a type of cell division that produces gametes – cells that contain half the number of chromosomes than the parent cell. b. In external fertilization, the union of gametes occurs outside the body whereas, in internal fertilization, the union of gametes occurs inside the body. Ferns are classified by the arrangement of the sori and shape of the indusium. Fundamental to sexual reproduction is the method by which gametes are brought together. meiosis, not mitosis). penis) to introduce the sperms into the female body. The mature sporophyte growing on top of the gametophyte produces spores by meiosis that when they spread by wind and find favorable conditions germinate into anew gametophyte. Plants and some algae have a two-generation of life cycle called the alternative generation that involves meiosis. Are the spores produced by the fern sporophyte formed by mitosis or meiosis? Are the sporangia haploid or diploid in Horestails? Does pumpkin pie need to be refrigerated? Sperms swim in moist environments from the antheridia to an egg at the base of the archegonium. 1.

Sporophytes can reproduce either by vegetative cloning via their rhizomes or through spore formation via meiosis. The dominant generation is larger and exists for a long period of time. Why must meiosis and not mitosis be used to produce gametes? When the egg is fertilized, the developing embryo is retained within the archegonia. 3. Previous question Next question Transcribed Image Text from this Question. Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. Are the gametes produced by mitosis or meiosis? Reasons why ferns are more adapted to terrestrial life than mosses. In megaspore meiosis occurs 1 time and mitosis 3 time and in microspore meiosis 1 and mitosis 2 times. The life cycle of human and most animals follow the plant below: Alternative generation is a life cycle the diploid and haploid generation follow one another and the two-generation are dissimilar or the alternation of a sexual phase and an asexual phase in the life cycle of an organism.
