  • Question 1
    1 / -0
    Columella is a structure found in
    Solution
    Columella is present on the tip of long stalk known as sporangiophore, present in the Rhizopus. It supports the Sporangium which has asexual spores. It helps nutrient exchange between the active protoplasm below and the developing spores inside the upper portion of the sporangial head. Sporangiophores arise among distinctive, root-like rhizoids. 
    So, the correct answer is option B.
  • Question 2
    1 / -0
    In Mucor/ Rhizopus, isogamy occurs between
    Solution

  • Question 3
    1 / -0
    Plasmogamy is fusion of 
    Solution
    The sexual reproduction of fungi involves three phases, namely plasmogamy, karyogamy and meiosis. In plasmogamy, there is a fusion of two protoplasts that brings together two compatible nuclei within the same cell. This pair of nuclei is called as a dikaryon (resulting cell becomes bi-nucleate).
    Thus, there is fusion of two haploid cells without nuclear fusion. In case of lower fungi, plasmogamy is almost immediately followed by karyogamy but in higher fungi these two processes may be separated in time. so option B is correct.
  • Question 4
    1 / -0
    Rhizopus reproduces sexually through
    Solution
    Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. Rhizopus produce by forming asexual and sexual spores. In a sexual reproduction, sporangiopores are produced inside a spherical structure, the sporangium. In sexual reproduction, a dark zygospore is produced at the point where two compatible mycelia fuse.
    Thus, the correct answer is option (A), 'Sporangiospores'.
  • Question 5
    1 / -0
    Mycelium of Mucor / Rhizopus is
    Solution
    The vegetative body in Mucor/Rhizopus is a coenocytic which forms white and cotton growth on the substratum because they lack cross walls or septa.
    Hence the correct option is D. 
  • Question 6
    1 / -0
    Fungi are:
    Solution
    All fungi are heterotrophic, which means that they get the energy they need to live from other organisms. Like animals, fungi extract the energy stored in the bonds of organic compounds such as sugar and protein from living or dead organisms.
    Hence the correct answer is option A. 
  • Question 7
    1 / -0
    "Torula condition" occurs in :
    Solution

  • Question 8
    1 / -0
    Zygospore of Rhizopus develops into
    Solution
    • In Rhizopus, the male (+) and female (-) gametangia fuse and the gametangial copulation leads to the formation of a zygospore.
    •  On germination, the innermost layer comes out after cracking the outer walls and produces a promycelium. With further develop­ment, the promycelium is differentiated into a lower stalk-like sporangiophore and an upper spherical sporangium. Hence, the Zygospore of Rhizopus develops into Promycelium.
    • So, the correct answer is "Promycelium
  • Question 9
    1 / -0
    Which one is not related to perfect stage of fungus ____________.
    Solution
    • Mitospores are asexual spores, for example - conidia in Penicillium. That is, they are produced by a single parent and do undergo meiosis.
    • These are non-motile spores produced exogenously from the tips and sides of hyphae. Hence, Mitospores is not related to the perfect or sexual reproduction stage of the fungus.
    • So, the correct answer is "Mitospores'.
  • Question 10
    1 / -0
    Sexual reproduction in Rhizopus occurs through _________.
