Sample questions

1. What is the main purpose of reproduction in organisms?

   1. To ensure the continuation of a species
   2. To increase food resources
   3. To decrease population size
   4. To exchange genetic material with the environment
   Show answer

   Answer: A. To ensure the continuation of a species

   Reproduction is the biological process by which new individual organisms are produced, ensuring the continuation of genetic material and the survival of the species.

2. What is a zygote?

   1. A single-celled organism
   2. The fertilized egg cell
   3. A component of the ovary
   4. An unfertilized egg cell
   Show answer

   Answer: B. The fertilized egg cell

   A zygote is the initial cell formed when two gamete cells are joined by means of sexual reproduction. It is the fertilized egg cell.

3. Which organism is known for reproducing by budding?

   1. Amoeba
   2. Hydra
   3. Plasmodium
   4. Yeast
   Show answer

   Answer: B. Hydra

   Hydra reproduces by budding, a form of asexual reproduction where a new organism develops as a bud due to cell division.

4. Why is genetic variation important in sexual reproduction?

   1. Ensures uniformity
   2. Prevents evolution
   3. Encourages biodiversity
   4. Limits adaptability
   Show answer

   Answer: C. Encourages biodiversity

   Sexual reproduction introduces genetic variation through the combination of different alleles, which is crucial for adaptation and biodiversity.

5. How does pollination occur in wind-pollinated plants?

   1. Insects transfer pollen
   2. Birds carry pollen
   3. Pollen is carried by wind
   4. Plants self-pollinate
   Show answer

   Answer: C. Pollen is carried by wind

   In wind-pollinated plants, pollen is light and produced in large quantities, allowing it to be carried by the wind to reach female structures of other plants.
