  • Question 1
    1 / -0

    Double fertilisation involves

    Solution

    One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing syngamy. This results in the formation of a diploid cell, the zygote. The other male gamete moves towards the two polar nuclei located in the central cell and fuses with them to produce a triploid primary endosperm nucleus. This is called triple fusion. This completes the process of double fertilisation.

     

  • Question 2
    1 / -0

    Fusion of a male gamete with an egg in the embryo sac is called

    Solution

    One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing syngamy.

     

  • Question 3
    1 / -0

    Starting from the innermost part, the correct sequence of parts in an ovule are

    Solution

    The structure of an ovule shows that eggs are the innermost part of the ovule followed by the embryo sac, which contains the egg apparatus, followed by the nucellus, which is surrounded by integuments.

     

  • Question 4
    1 / -0

    Among the terms listed below, those that are not technically correct names for a floral whorl are (i) Androecium   (ii) Carpel (iii) Corolla   (iv) Sepal

    Solution

    A typical angiospermic flower consists of four whorls attached onto the receptacle—calyx, corolla, androecium and gynoecium.

     

  • Question 5
    1 / -0

    The female gametophyte in angiosperm is

    Solution

    The functional megaspore forms the female gametophyte or embryo sac.

     

  • Question 6
    1 / -0

    The phenomenon wherein, the ovary develops into a fruit without fertilisation is called

    Solution

    Some plants are able to produce fruits without fertilisation. This phenomenon is called parthenocarpy.

     

  • Question 7
    1 / -0

    Entomophilous flowers are pollinated by

    Solution

    Entomophily is pollination by insects.

     

  • Question 8
    1 / -0

    In some plants, the anthers and stigma grow and mature at the same time. This phenomenon is called

    Solution

    Anther and stigma of bisexual flowers of some plants mature at the same time. They are brought close to each other to ensure self-pollination. This is called homogamy.

     

  • Question 9
    1 / -0

    Parthenocarpic fruits are developed by the application of

    Solution

    In horticultural techniques, parthenocarpic fruits are artificially developed by the application of low concentration of auxins and gibberellins.

     

  • Question 10
    1 / -0

    In angiosperms, functional megaspore develops into

    Solution

    After megasporogenesis, the megaspore develops into the female gametophyte or the embryo sac in a process called megagametogenesis.
