The blastomeres in the blastocyst are arranged into an outer layer ____A____ and inner group of cells attached to trophoblast called the ___B____ .

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.

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.

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.

given below are four statements (i)-(iv) reagarding embryonic development in humans. (i). Cleavage divisions about considerable increase I the mass of protoplasm (ii). With more cleavage divisions, the resultant blatomeres become smaller and smaller. (iii). the blastomeres in the blastocyst are arranged into two layers, trophoblast and endometrium. (iv). Cleavage divisions result in a solid ball of cells called morula. Which of the above two statemetns are correct?
