Question:

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.

Options:

Both A and R are true, and R is the correct explanation of A.

Both A and R are true, but R is not the correct explanation of A.

A is true, but R is false.

A is false, but R is true.

Correct Answer:

Both A and R are true, but R is not the correct explanation of A.

Explanation:

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. This statement is true because the penis contains erectile tissue that becomes filled with blood, causing erection which helps in insemination.

Reason (R): The enlarged end of the penis, called the glans penis, is covered by a loose fold of skin called the foreskin. This statement is also true because the glans penis is covered by the foreskin (prepuce).

How the Reason does not explain the Assertion: The Assertion talks about erectile tissue and its role in erection, whereas the Reason describes the structure of the glans penis and foreskin. The presence of foreskin does not explain how erection occurs or how insemination is facilitated.

NCERT: The male reproductive system is located in the pelvis region . It includes a pair of testes alongwith accessory ducts, glands and the external genitalia. The penis is the male external genitalia. It is made up of special tissue that helps in erection of the penis to facilitate insemination. The enlarged end of penis called the glans penis is covered by a loose fold of skin called foreskin. The male accessory glands include paired seminal vesicles, a prostate and paired bulbourethral glands. Secretions of these glands constitute the seminal plasma which is rich in fructose, calcium and certain enzymes. The secretions of bulbourethral glands also helps in the lubrication of the penis
