  • Question 1
    1 / -0
    For commercial propagation of banana and ginger which of the following parts are utilised respectively?
    Solution
    A sucker is a plant growth that develops from the rootstock of a plant that has undergone grafting. A sucker does not originate from a seed but instead it grows from the base of the root of the plant at a certain distance away from the plant. Eg. Banana, lilac, raspberry, etc. 
    A rhizome (also known as rootstocks) is a type of plant stem situated either at the soil surface or underground that contains nodes from which roots and shoots originate. Rhizomes are unique in that they grow perpendicular, permitting new shoots to grow up out of the ground. Eg. Ginger, turmeric, asparagus, etc.  
    So, the correct answer is ' Sucker, Rhizome'.
  • Question 2
    1 / -0
    Rhizome can be?
  • Question 3
    1 / -0
    Zea mays plants is:
    Solution
    Zea mays, more commonly referred to as maize contain both male and female reproductive structures and reproduce by both cross-pollination and self-pollination, hence it is monoecious.
    So the correct answer is 'Monoecious'.
  • Question 4
    1 / -0
    Second male gamete unites with two polar nuclei to form ________.
  • Question 5
    1 / -0
    Vegetative propagation in onion occurs by
    Solution
    For plants such as onions, garlic, tulip, daffodil, and hyacinth, the bulb is the unit of vegetative propagation. The stem is shortened down to a disc, often called the basal plate from which roots arise around the edge.

    So, the correct answer is 'Bulb'.

  • Question 6
    1 / -0
    Read the following statements $$1$$ and $$2$$ and identify the correct one.
    $$(1)$$ In bees parthenogenetic zygote develops into monoploid male
    $$(2)$$ The fertilised egg develops into diploid female.
    Solution
    Parthenogenesis is a form of asexual reproduction in which an unfertilized egg develops into a new individual. The egg develops into a haploid male which is the drone. 
    Queen honey bee produces eggs which after fertilization with sperm received from drone results in the formation of a female honey bee as offspring. This is an example of sexual reproduction. Hence fertilized egg develops into a diploid female. 
    Thus the correct answer is option D. 
  • Question 7
    1 / -0
    Sexual spores produced by Penicillium
  • Question 8
    1 / -0
    Amoeba and Yeast can reproduce asexually because: 
    Solution
    • Unicellular organisms have relatively simple organizations. So, the asexual mode of reproduction is common in them. In Amoeba it occurs by binary fission and in yeast by budding. 

    So, the correct answer is 'they are unicellular and simple body structure'
  • Question 9
    1 / -0
    Mark the correct one.
    Solution
    • Balaenoptera which designates genus is a combination of two Latin words, "balaena" (meaning whale) and "pteron" (meaning fin). It thus means a whale having a dorsal fin so as to distinguish from balaena (meaning whale without dorsal fin). "Musculus" designating species is a Latin word originally meaning a "mouse.
    • In mammals, reptiles, birds, and some types of fish the gametes meet inside of the female's body. This is called internal fertilization. 
    • As Balaenoptera is a mammal the fertilization in balaenoptera is internaL.
    • so, the correct answer is 'Balaenoptera - internal fertilization'.
  • Question 10
    1 / -0
    Spore formation is the most common asexual method of reproduction in:
    Solution
    In both sexual and asexual reproduction, fungi reproduce by spore formation. Spores are dispersed from the parent by either wind or animals. On getting a suitable substratum, these spores grow and form new individuals.
