FAQs on Class 10 Science How do organism reproduce Video Lecture

1. How do organisms reproduce?
Ans. Organisms reproduce through various methods such as sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of male and female gametes to form a zygote, which develops into a new organism. Asexual reproduction, on the other hand, does not involve the fusion of gametes and can occur through processes like binary fission, budding, spore formation, and vegetative propagation.
2. What is sexual reproduction?
Ans. Sexual reproduction is a type of reproduction where two parents, typically a male and a female, contribute genetic material to produce offspring. It involves the fusion of specialized cells called gametes, which are produced by each parent. The male gamete (sperm) fuses with the female gamete (egg) to form a zygote, which develops into a new organism with a combination of genetic traits from both parents.
3. What is asexual reproduction?
Ans. Asexual reproduction is a type of reproduction where a single parent organism produces offspring without the involvement of gametes or the fusion of genetic material. In asexual reproduction, the offspring are genetically identical or clones of the parent organism. This type of reproduction occurs through various methods such as binary fission (division of a parent organism into two equal parts), budding (outgrowth from the parent organism), spore formation (release of specialized cells capable of developing into new organisms), and vegetative propagation (growth of new plants from vegetative parts like roots, stems, or leaves).
4. How does binary fission occur?
Ans. Binary fission is a method of asexual reproduction commonly observed in unicellular organisms like bacteria and protozoans. During binary fission, the parent organism divides into two equal parts, each of which grows into a new organism. The process involves the replication of genetic material, followed by the elongation of the parent cell and the division of cytoplasm and organelles. Finally, two genetically identical daughter cells are formed, each having a complete set of genetic material.
5. What is vegetative propagation?
Ans. Vegetative propagation is a type of asexual reproduction in plants where new individuals are formed from vegetative parts like roots, stems, or leaves. This method allows plants to reproduce without the involvement of seeds and can occur naturally or be induced artificially. Examples of vegetative propagation include cutting, layering, grafting, and tissue culture. This process allows the new plants to be genetically identical to the parent plant, ensuring the preservation of desirable traits.
