Sample questions

1. Which part of a flower typically contains the pollen?

   1. Petal
   2. Sepal
   3. Anther
   4. Stigma
   Show answer

   Answer: C. Anther

   The anther is the part of the stamen that contains the pollen grains, which are essential for fertilization.

2. Which method of asexual reproduction involves the formation of a new individual from a fragment of the parent body?

   1. Budding
   2. Spore formation
   3. Fragmentation
   4. Binary fission
   Show answer

   Answer: C. Fragmentation

   Fragmentation is a mode of asexual reproduction where the parent organism breaks into several fragments, and each fragment develops into a new individual. This is common in some algae and fungi.

3. Self-pollination occurs when pollen is transferred:

   1. Between flowers of different plants
   2. From the anther to the stigma of the same flower or another flower on the same plant
   3. By insects to the stigma
   4. By wind to the stigma of a different species
   Show answer

   Answer: B. From the anther to the stigma of the same flower or another flower on the same plant

   Self-pollination encompasses both autogamy (pollen transfer within the same flower) and geitonogamy (pollen transfer between different flowers of the same plant).

4. Which part of the flower is usually brightly colored to attract pollinators?

   1. Sepal
   2. Petal
   3. Pistil
   4. Stamen
   Show answer

   Answer: B. Petal

   Petals are often brightly colored, fragrant, and may produce nectar to attract insects, birds, or other animals that help in pollination.

5. The process by which a new plant grows from a piece of stem or leaf is called:

   1. Seed propagation
   2. Vegetative propagation by cuttings
   3. Spore formation
   4. Fertilization
   Show answer

   Answer: B. Vegetative propagation by cuttings

   Taking cuttings from stems or leaves and planting them to grow new plants is a common method of artificial vegetative propagation.
