  • Question 1
    1 / -0

    Which one forms the endosperm

    Solution

    Endosperm is the product of fusion of two polar nuclei with one male gamete. Endosperm provides nourishment to growing embryo.

  • Question 2
    1 / -0

    In which of the following plants endosperm is completely used up by developing embryo

    Solution

    Endosperm is present around the growing embryo. It provides nutrition to the growing embryo. In leguminous plants, it is completely consumed by the embryo and nothing remains in seed as in pea.

  • Question 3
    1 / -0

    Endosperm type in which first division of primary endosperm nucleus and few subsequent division are not accompanied by wall formation is called

    Solution

    PEN (primary endosperm nucleus) divides into two nuclei and subsequent division of nucleus produce large number of nucleus without cell wall formation. These types of endosperm are called free nuclear type of endosperm.

  • Question 4
    1 / -0

    Number of nuclei participating in double fertilisation is

    Solution

    Double fertilisation involves fusion of one male gamete with egg during Syngamy and fusion of two polar nuclei with other male gametes. So, total 5 nuclei are involved in double fertilisation.

  • Question 5
    1 / -0

    One out of two male gametes fuses with two polar nuclei to produce PEN, which is abbreviation of

    Solution

    Two polar nuclei and one male gamete fuse with together to form primary endosperm nucleus which is abbreviated as PEN.

  • Question 6
    1 / -0

    Horse shoe shaped embryo sac is present in which type of ovule

    Solution

    Embryo sac is of different shape depending upon family to which it belongs. Different ovules have different shaped embryo sac. Amphitropous ovule contain horse shoe shaped embryo sac.

  • Question 7
    1 / -0

    The cotyledon of maize grain is technically called as

    Solution

    Maize grain is monocotyledonous, having single cotyledon. This cotyledon is also called as scutellum

  • Question 8
    1 / -0

    The endosperm in angiospermic plants develops from

    Solution

    Endosperm provide nutrient to growing embryo. It is formed by fusion of two polar nuclei and one male gamete. The polar nuclei develop from secondary nucleus.

  • Question 9
    1 / -0

    The fusion of male gamete with an egg in the embryo sac is called

    Solution

    Each pollens grain produces two male gametes. One male gamete fuse with egg to form zygote. This fusion is called Syngamy. The other male gamete fuses with two polar nuclei to form endosperm. This fusion is called triple fusion.

  • Question 10
    1 / -0

    The portion of embryonic axis of monocots above the level of attachment of scutellum is called as

    Solution

    Coleoptile is sheath like structure that protects the developing plumule. It is present above the scutellum during the embryonic development.
