Question

Read the assertion (A) and reason (R) carefully to mark the correct option out of the options given below:
A. There are some plants which have in their life-cycles neither the process of fertilization nor they have meiosis.
R. In these plants, the vegetative or somatic plant body helps in the propagation of the plant.

• A. Both the Assertion and the Reason are true and the reason is a correct explanation of the assertion.
• B. Both the Assertion and Reason are true but the reason is not a correct explanation of the assertion.
• C. The Assertion is true but the Reason false.
• D. Both the Assertion and Reason are false.
• E. The assertion is false but reason is true.

Answer 1

The correct option is A Both the Assertion and the Reason are true and the reason is a correct explanation of the assertion.

Organisms reproduce for perpetuation of species because individuals have a limited life span. Organisms may reproduce sexually as well as asexually. The sexual reproduction involves formation of haploid gametes through the process of reduction division or meiosis. The haploid gametes fuse during fertilization to form diploid zygote. Thus, restoring the normal ploidy. The asexual reproduction does not involves gamete formation through meiosis or their fertilization. The vegetative propagation in plants is a type of asexual reproduction in which plant body is propagated directly from some vegetative part of adult plant.

Therefore, the correct answer is option A.
