Question

Match the following items of Column-I with that of Column-II:

Column-I	Column-II
(a) Trophoblast	(iv) Outer layer of blastocyst
(b) Implantation	(i) Embedding of blastocyst in the endometrium
(c) Inner cell mass	(ii) Group of cells that would differentiate as embryo
(d) Morula	(iii) Embryo with 8–16 blastomeres

Choose the option that matches Column-I with Column-II correctly:

• A. A
• B. B
• C. C
• D. D

Hint:

Remember: Trophoblast → outer layer, Inner cell mass → future embryo, Morula → 8–16 cells stage.

Answer 1

The Correct Option is A

Step 1: Trophoblast is the outer layer of the blastocyst → (a) → (iv)
Step 2: Implantation is the embedding of blastocyst into the endometrium → (b) → (i)
Step 3: Inner cell mass forms the embryo → (c) → (ii)
Step 4: Morula is an embryo stage with 8–16 blastomeres → (d) → (iii)
