The blastomeres in the blastocyst are arranged into an outer layer called ul((A)) and an inner group of cells attached to trophoblast called ul((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.
