  • Assertion: The embryo with 8 to 16 blastomeres is called a morula. Reason: The blasometeres in the morula are arranged into an outer layer called trophoblast and an inner group of cells attached to trophoblast called the inner cell mass.

    A
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
    B
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
    C
    If assertion is true but reason is false.
    D
    If both assertion and reason are false.

  • Read the passage and answer the questions: Implantation is the embedding of the blastocyst into the endometrium of the uterus. Blastocyst is a ball of cells with a large, fluid-filled cavity called the blastocoel. The blastomeres in the blastocyst are arranged into an outer layer called trophoblast and inner cell mass. With the formation of blastocoel, morula is converted to blastula which is called blastocyst in mammals. The ectoderm cells will form the........

Blastocyst is a ball of cells with a large, fluid-filled cavity called the blastocoel. The blastomeres in the blastocyst are arranged into an outer layer called trophoblast and inner cell mass. With the formation of blastocoel, morula is converted to blastula which is called blastocyst in mammals. Assertion (A): Blastocyst undergoes gastrulation to form three germinal layers. Reason (R): This involves cell movements (morphogenetic movement) that help to attain new shape and morphology of embryo.

    A
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion(A).
    B
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
    C
    Assertion (A) is true but reason (R) is false.
    D
    Assertion (A) is false but reason (R) is true.

    Zygote undergoes cleavage while moving through the isthmus of the oviduct towards the uterus and forms daughter cells called blastomeres. The embryo with 8 to 16 blastomeres is called a ____A_____which continues to divide to form ____B_____ in uterus. The blastomeres in the____B_____are arranged into an outer layer called____A_____and an inner group of cells called the inner cell mass.

    In which stage does the embryo differentiate into trophoblast and an inner group of cells ?
