NCERT Class 10 Science How do Organisms Reproduce?: In-text questions (page 114) Solutions
AI-written, checked on 23 Oct 2026
Solutions written by Shishya, checked — not the board's official answers
Step-by-step working for every question of In-text questions (page 114) in NCERT's Class 10 Science book, chapter “How do Organisms Reproduce?”, written by Shishya. Each question is in our own short words; open the NCERT chapter for the exact wording and figures.
How these were checked: the solutions were drafted with AI and then read and corrected on 23 Oct 2026. Every numerical final answer is recomputed from the question's own numbers by a calculator check that runs before each release; proofs and explanations were read, not machine-checked. The NCERT textbook is the authority — if something here disagrees with it, follow the book.
Tap “why?” under a step to see the textbook rule it uses — from Shishya's fixed list of NCERT Class 9-10 rules, not written by AI for this page. A step without one has no rule from the list yet.

What is the importance of DNA copying in reproduction?
- DNA carries the genetic information that determines the characteristics of an organism.
- During reproduction, this genetic material must be passed from the parent to the offspring.
- DNA copying ensures that the offspring receives an exact copy of the parent's genetic instructions.
- This process maintains the continuity of life and ensures that the offspring resembles the parent.
- It also allows for the transmission of traits and variations across generations.
Answer: DNA copying is important in reproduction because it ensures the transmission of genetic information from parents to offspring, maintaining the continuity of life and passing on traits.

Why is variation beneficial to the species but not necessarily to the individual?
- Variation refers to the differences in traits among individuals of a species.
- For an individual, a specific variation may be harmful or disadvantageous in its current environment, leading to poor survival.
- However, for the species, these variations provide a wider range of traits to adapt to changing environmental conditions.
- If the environment changes, individuals with beneficial variations are more likely to survive and reproduce.
- This ensures the survival of the species over generations, even if some individuals with less suitable variations die out.
Answer: Variation is beneficial to the species as it aids in adaptation to changing environments, ensuring long-term survival, but not necessarily to the individual as a specific variation may be disadvantageous in the current environment.
