FAQs on Reproduction in Animals Class 8 Worksheet Science Chapter 6

1. What is reproduction in animals?
Ans. Reproduction in animals refers to the biological process through which new individuals of the same species are produced. It involves the transfer of genetic material from parent organisms to their offspring, ensuring the continuity of the species.
2. What are the different modes of reproduction in animals?
Ans. Animals employ various modes of reproduction, including sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of male and female gametes, resulting in the formation of offspring with a unique combination of genetic traits. Asexual reproduction, on the other hand, does not involve the fusion of gametes and leads to the production of genetically identical offspring, also known as clones.
3. How do animals reproduce through sexual reproduction?
Ans. In sexual reproduction, animals produce specialized reproductive cells called gametes. The male gamete, or sperm, is produced by the male organism, while the female gamete, or egg, is produced by the female organism. These gametes fuse during fertilization, forming a zygote. The zygote then undergoes development and eventually grows into a new individual.
4. What are the advantages of sexual reproduction in animals?
Ans. Sexual reproduction offers several advantages to animals. Firstly, it promotes genetic diversity, which enhances the adaptability of a species to changing environments. It also helps in the elimination of harmful genetic mutations through recombination. Additionally, sexual reproduction allows for the exchange of genetic material between individuals, leading to the creation of unique combinations of traits in offspring.
5. Can animals reproduce through asexual reproduction?
Ans. Yes, animals can reproduce through asexual reproduction. Some animals, such as certain species of insects, reptiles, and fish, are capable of asexual reproduction. This process typically involves the production of offspring without the involvement of gametes. Asexual reproduction allows for rapid population growth and is advantageous in stable and favorable environments. However, it does not contribute to genetic diversity.
