Answer to Problem 1MC

Correct answer:

In a reptile egg, the extra embryonic membrane that encloses the embryo in a watery environment is the amnion.

Therefore, option (b) is correct.

Option (b) is given as “amnion”.

Explanation of Solution

Justify reasons for the correct statement:

Amnion layer encloses the fertilized embryo in a watery environment containing the amniotic fluid. It gives protection during the stages of development of the egg. It forms the ectoderm, mesoderm and endoderm during the fertilization of the egg.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “allantois”.

Allantois forms separate sac which secretes the metabolic wastes from the human body. Hence, it is a wrong answer.

Option (c) is given as “chorion”.

It is present near the egg shell and helps in the exchange of gases like oxygen and carbon-dioxide. Hence, it is a wrong answer.

Option (d) is given as “yolk-sac”.

It contains the egg yolk. Hence, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Reptile amniotic eggs contain amnion layer with watery environment which prevents the egg under shock and stress.
