  • Question 1
    1 / -0

    Three germ layers are formed during which stage of Embryonic development.

    Solution

    After blastocyst form in Blastulation with totipotent stem cell than germ layers form.

  • Question 2
    1 / -0

    Movement of blastomeres usually seen in which Embryonic stage :-

    Solution

    Once trophoblast form cells of blastomere move 

  • Question 3
    1 / -0

    Solution

    The first movements of the foetus and appearance of hair on the head are usually observed during the fifth month

  • Question 4
    1 / -0

    In which stage rate of cell-division decrease?    

    Solution

    As gastrulation occur rate of cell division decrease 

  • Question 5
    1 / -0

    Fate map of embryo is prepared in which stage?

    Solution

    A fate map is a diagram of an egg or blastula, indicating the fate of each cell or region, at a later stage of development. Fate maps are essential tool in most embryological experiments.

    1 / -0

    Solid ball of cell produced by repeated cleavage is called

    Solution

    Mitotic division in Zygote lead to formation of Morula

    1 / -0

    Gastrulation is a process

    Solution

    In gastrulation differentiation of germ layer occur

    1 / -0

    The first indication of division of labour in the blastomeres appear at

    Solution

    Germ layers first form in gastrulation

  • Question 9
    1 / -0

    Sexually reproducing multicellular animals start their development from -

    Solution

    Zygote is first stage after fertilization which undergo mitosis 

  • Question 10
    1 / -0

    Correct sequence in development is -

    Solution

    Fertilization lead to zygote formation followed by Morula, blastocyst and Gastrula 

  • Question 11
    1 / -0

    Preparation of cell differentiation are completed in-

    Solution

    Blastula also have totipotent stem cell

  • Question 12
    1 / -0

    What is true for cleavage :-

    Solution

    With each division size of cell keep on decreasing as growth not occur 

  • Question 13
    1 / -0

    Cleavage start in human in

    Solution

    Fertilization occur in fallopian tube in ampulla region at same location Cleavage start 

  • Question 14
    1 / -0

    Type of cleavage in an egg is determined by :    

    Solution

    Yolk is stored food material on the basis of type of division depend after fertilization 

  • Question 15
    1 / -0

    Identical twins will be produced when :

    Solution

    After zygote start Cleavage cells are known as Blastomere and if they separate and can get implanted with two embryo 

  • Question 16
    1 / -0

    Division of human egg is :

    Solution

    Since yolk absent so division is holoblastic Equal 

  • Question 17
    1 / -0

    The embryo with 8 to 16 blastomeres is called :

    Solution

    Zygote divide to form 8-16 cell stage known as morula

    1 / -0

    Stem cells are found in :-    

    Solution

    In blastocyst the inner cell mass is totipotent stem cell and it undergo division and differentiation
