FAQs on Class 10 Science Chapter 7 MCQ : How do Organisms Reproduce? MCQs Quiz

1. Why is DNA copying essential during reproduction?
   DNA copying is essential because it carries the genetic information from parents to offspring, ensuring the continuity of species and creating variations for evolution.
2. What is vegetative propagation?
   Vegetative propagation is an asexual method of reproduction in plants where a new plant grows from a vegetative part like the root, stem, or leaf (e.g., potato eyes, rose cuttings).
3. What is the role of the seminal vesicles and the prostate gland?
   The seminal vesicles and prostate gland produce fluids that nourish the sperms and provide a medium for their transport, making up the semen.
4. Define pollination.
   Pollination is the process of transferring pollen grains from the anther of a stamen to the stigma of a pistil, either within the same flower or between different flowers.
5. What is “binary fission”?
   Binary fission is a type of asexual reproduction where an organism divides into two equal halves, commonly seen in organisms like Amoeba and Paramecium.
6. How does the embryo get nourishment inside the mother’s body?
   The embryo gets nourishment through the placenta. The villi on the placenta provide a large surface area for the transfer of glucose and oxygen from the mother’s blood to the embryo.
7. What are the different methods of contraception?
   Contraceptive methods include mechanical barriers (condoms), hormonal methods (pills), intrauterine devices (IUDs), and surgical methods (vasectomy/tubectomy) to prevent pregnancy.
8. What happens if the egg is not fertilized in a human female?
   If the egg is not fertilized, the thick and spongy lining of the uterus slowly breaks down and is shed out through the vagina as blood and mucus, known as menstruation.
9. What is the main difference between zygote and fetus?
   A zygote is the single-celled structure formed by the fusion of sperm and ovum, whereas a fetus is the developing multicellular stage after the zygote implants in the uterus and develops organs.
10. Name two sexually transmitted diseases (STDs).
    Two examples of STDs are Gonorrhea and HIV (AIDS).
