Question

Assertion (A): The testes of males are primary sex organs.

Reason (R): The ovaries of females are secondary sex organs.

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.

Answer 1

A is true but R is false.

Explanation:

The testes are the primary sex organs (gonads) in males because they produce sperms and the male sex hormone testosterone. Therefore, the Assertion (A) is true.

The ovaries are also primary sex organs (gonads) because they produce ova (eggs) and the female sex hormones oestrogen and progesterone. Secondary sex organs include structures such as the uterus, fallopian tubes, vagina, and external genitalia. Therefore, the Reasons (R) is false.

Hence, A is true but R is false.
