Assertion: Asexual reproduction is also called blastogenesis.
Reason: In asexual reproduction, there is no fusion of gametes.
Explanation:
Asexual reproduction is a type of reproduction where offspring are produced without the involvement of gametes or the fusion of genetic material from two parents. It is commonly observed in many organisms such as bacteria, fungi, plants, and some animals. Blastogenesis is a specific form of asexual reproduction where new individuals are formed from outgrowths or buds on the parent organism.
Assertion is true: Asexual reproduction is also called blastogenesis. This is because blastogenesis is one of the mechanisms by which asexual reproduction can occur.
Reason is true: In asexual reproduction, there is no fusion of gametes. Gametes are specialized reproductive cells that carry genetic material from two parents. However, in asexual reproduction, offspring are produced by a single parent without the involvement of gametes.
Reason is not a correct explanation of the assertion: While it is true that asexual reproduction does not involve the fusion of gametes, it is not the defining characteristic of blastogenesis. Asexual reproduction can occur through various mechanisms, such as binary fission, budding, fragmentation, and parthenogenesis. Blastogenesis specifically refers to the formation of new individuals from buds or outgrowths on the parent organism, regardless of whether gametes are involved or not.
Therefore, both the assertion and the reason are true, but the reason is not a correct explanation of the assertion. The correct answer is option B.
