Questions and Answers

What is the main reason flowers produce an enormous amount of pollen compared to the number of ovules available for pollination?

  • To conserve energy by producing excess pollen
  • To decrease the chances of attracting abiotic agents for pollination
  • To increase the chances of successful pollination due to uncertainties in pollen contact with stigmas (correct)
  • To limit the number of pollinators attracted to the flowers
  • Which feature do wind-pollinated flowers typically possess to aid in the dispersal of pollen grains by wind?

  • Multiple ovules in each ovary
  • Highly scented petals to attract insects
  • Large and sticky stigma to capture pollen grains
  • Exposed stamens for easy pollen dispersal (correct)
  • Why do wind-pollinated flowers usually have a single ovule in each ovary?

  • To allow better focus on attracting wind currents for pollination
  • To prevent wastage of pollen grains (correct)
  • To conserve energy by producing fewer ovules
  • To reduce the chances of successful pollination
