Answer : 4. "Insect"
Explanation :
Fragrant flowers attract pollinators like bees, butterflies, and birds with their pleasant scent. These pollinators visit the flowers to feed on nectar or collect pollen. During their visits, they unintentionally transfer pollen from one flower to another, facilitating pollination. This process enables the plant to reproduce and produce seeds. Different plants rely on specific pollinators, ensuring their reproductive success and genetic diversity within the ecosystem.

Answer : 2. "Sykes"
Explanation :
Certain plants, like gymnosperms, produce seeds but lack fruits. Gymnosperms, including pine trees and cycads, have exposed seeds on cone scales, distinguishing them from angiosperms, which produce seeds enclosed within fruits. The absence of a fruit covering the seed is a characteristic feature of gymnosperms, a group of seed-producing plants.
