Questions and Answers

What is the advantage of germination of seeds for plants?

  • Seeds ensure asexual reproduction, leading to genetic diversity.
  • Seeds lead to regeneration of lost body parts in plants.
  • Seeds contain the future plant embryo, ensuring continuity of the plant species. (correct)
  • Seeds facilitate vegetative propagation by forming new individuals.

    • Why is sexual reproduction significant for humans?

  • Sexual reproduction leads to genetic diversity and adaptability to changing environments. (correct)
  • Sexual reproduction allows for rapid increase in population size.
  • Sexual reproduction guarantees asexually reproduced offspring.
  • Sexual reproduction ensures identical offspring with no genetic variation.

    • What is a limitation of regeneration in complex organisms like humans?

  • Regeneration leads to rapid healing of wounds.
  • Regeneration cannot replace highly specialized organs like the heart or brain. (correct)
  • Regeneration allows for complete regrowth of lost body parts.
  • Regeneration results in immediate genetic variation.
