Solution


Q.

Assertion: Placenta is connected to the embryo through an umbilical cord which helps in the transport of substances to and from the embryo.
Reason: Placenta acts as an endocrine tissue.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.  
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.  
3 Assertion is true but Reason is false.  
4 Assertion is false but Reason is true.  

Ans.

(2)

Placenta performs both the given functions. But they are not related to each other. Being an endocrine tissue it releases hormones like progesterone, estrogen and others, but does not help in transport of materials to and from the embryo. Thus, both assertion and reason are correct but reason is not the correct explanation of the assertion.
