Question

Assertion (A): A zygote is formed by the fusion of male and female gametes whereas an embryo is formed by the repeated cell division of a zygote.

Reason (R): The secretions of seminal vesicles and prostate gland provide nutrition to the sperms and also make their further transport easier.

Options

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

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

• A is true but R is false.

• A is false but R is true.

Answer 1

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

Explanation:

A zygote is formed by the fusion of male and female gametes. The zygote undergoes repeated cell divisions to develop into an embryo. Therefore, Assertion (A) is true.

The secretions of the seminal vesicles and prostate gland nourish the sperms and facilitate their transport. Therefore, Reason (R) is also true.

However, Reason (R) does not explain Assertion (A) because it describes the function of the seminal vesicles and prostate gland, not the formation of the zygote and embryo.

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