2. A farmer cuts the stem of a rose plant and plants it into soil, where it grows into a new plant. Which type of reproduction does this demonstrate, and why is it beneficial for farmers?
- Sexual reproduction; because it increases genetic variation
- Asexual reproduction; because it produces plants quickly and identically
- Fertilization; because it improves seed strength
- Spore formation; because it avoids using water
3. During a school experiment, students placed pollen grains from one flower onto the stigma of a flower on a different plant of the same species. What type of pollination is this and what advantage does it offer?

- Cross-pollination; increases genetic diversity
- Asexual reproduction; rapid cloning
- Hybridization; creates new species

- Spore formation; sexual reproduction
5. A student observed that spores from a fungus developed into new individuals without the need for gamete fusion. Which characteristic of spore formation does this highlight?
- It requires pollination
- It is a form of sexual reproduction
- It occurs in aquatic plants only
- It is a rapid asexual reproduction method
6. Why is vegetative propagation by leaves in plants like Bryophyllum considered efficient for survival in harsh environments?
- It reduces water requirement and occurs without seeds
- It promotes sexual diversity
- It requires high genetic variation
- It depends on external pollinators
7. During pollination, why is the stigma often sticky and elevated above the flower?
- To allow pollination by animals only
- To support fertilization directly
- To capture pollen efficiently from air or insects
- To store pollen grains
8. Analyze why seeds formed after fertilization are covered by fruits in many flowering plants.
- Fruits add taste and nutrition to seeds
- Fruits aid in seed dispersal and protection
- Fruits allow spore formation
- Fruits increase photosynthesis
