FAQs on REPRODUCTION (FULL CHAPTER) - CLASS 10 CBSE Video Lecture

1. What is reproduction?
Ans. Reproduction is the biological process by which new individuals of the same species are produced. It ensures the continuity of life on Earth and can be either sexual or asexual.
2. What is the difference between sexual and asexual reproduction?
Ans. Sexual reproduction involves the fusion of gametes (sperm and egg) from two parents, resulting in offspring with genetic variation. Asexual reproduction, on the other hand, does not involve the fusion of gametes and only one parent is involved. Offspring produced through asexual reproduction are genetically identical to the parent.
3. What are the different modes of asexual reproduction?
Ans. Asexual reproduction can occur through various modes such as binary fission, budding, fragmentation, spore formation, and vegetative propagation. These modes vary among different organisms and allow them to reproduce without the need for a mate.
4. How does sexual reproduction occur in humans?
Ans. Sexual reproduction in humans involves the fusion of a sperm cell from the male reproductive system with an egg cell from the female reproductive system. This process is known as fertilization and takes place in the fallopian tube. The fertilized egg then implants itself in the uterus, where it develops into an embryo.
5. Why is reproduction important for the survival of a species?
Ans. Reproduction is vital for the survival of a species as it ensures the continuation of the species over generations. Through reproduction, genetic diversity is maintained, allowing populations to adapt to changing environments. Additionally, reproduction allows for the transmission of traits and characteristics from one generation to the next, ensuring the preservation of the species' genetic information.
