Assertion (A): The penis is made up of special tissue that helps in erection to facilitate insemination.
Reason (R): The enlarged end of the penis, called the glans penis, is covered by a loose fold of skin called the foreskin.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Both A and R are true, but R is not the correct explanation of A.
Assertion (A): The penis is made up of special tissue that helps in erection to facilitate insemination. — True. The penis is the male external genitalia. It is made of special tissue that helps in erection, and erection allows insemination, that is, the release of semen into the vagina.
Reason (R): The enlarged end of the penis, called the glans penis, is covered by a loose fold of skin called the foreskin. — True. The enlarged tip of the penis is the glans penis, and a loose fold of skin called the foreskin covers it.
Why R does not explain A? A is about the tissue of the penis and its job in erection and insemination. R is about the shape of its tip: the glans penis and the skin that covers it. The foreskin is only a covering; it plays no part in making the penis erect. So both statements are correct, but R is not the explanation of A.
