Answers
Answer:
Therefore, the correct answer is option A.
Explanation:
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.
a) Both A and R are true and R is
a) Both A and R are true and R iscorrect explanation of the assertion.
- Asexual reproduction is known to be one of the simplest form of reproduction as it doesn't involves two parents to develop an offspring. A single parent has enough capacity to produce one.
- The offspring produced are exact copies of their parents which are also referred as clones. Hence, Asexual reproduction is a primitive type of reproduction. So, given assertion is true.
- Asexual reproduction involves only mitosis and not meiosis. Since, it's mitosis so theirs always the restoration of ploidy level of the organism.
- Hence, Both A and R are true and R is
- correct explanation of the assertion.
