Question

6) The Triassic Period was marked by the increase in number and variety of angiosperms. Insects also diversified enormously during the same period. What most likely fostered this coevolution? Now choose from one of the following options Why? aAngiosperms and insects benefited from the same mild climate. b There is no link. Species radiation in angiosperms and insects was independent. Plants evolved to attract beneficial pollinators and repel plant eating insects. Camouflaae! Insects evolved to hide in anaiosperms. Plants Home

Explanation / Answer

C

Angiosperms produce their gametes in separate organs, which are usually housed in a flower. Both fertilization and embryo development take place inside an anatomical structure that provides a stable system of sexual reproduction largely sheltered from environmental fluctuations. Flowering plants are the most diverse phylum on Earth after insects; flowers come in a bewildering array of sizes, shapes, colors, smells, and arrangements. Most flowers have a mutualistic pollinator, with the distinctive features of flowers reflecting the nature of the pollination agent. The relationship between pollinator and flower characteristics is one of the great examples of coevolution.

Angiosperms produce flowers with nectar and ample pollen to attract flower-visitors; in return, the flower-visitors transport pollen and effect pollination, so producing seeds. These plant-pollinator interactions are predicted to be the products of coevolution between plants and insects
