Sexual Reproduction in Flowering Plants

Question:

The characteristics of producing light, non-sticky pollen in large numbers and having long, feathery stigmas in a particular plant species facilitate pollination by which of the following?

Options:

Bird

Insects

Wind

Water

Correct Answer:

Wind

Explanation:

The correct answer is Option (3) – Wind

Wind pollination is a common form of abiotic pollination.

  • It requires light and non-sticky pollen grains that can be carried by wind currents.
  • Wind-pollinated flowers typically have well-exposed stamens, allowing easy dispersal of pollen into the air.
  • They often have large, feathery stigmas that are designed to efficiently capture airborne pollen grains.
  • Wind-pollinated flowers typically have a single ovule in each ovary.
  • Many wind-pollinated flowers are densely packed into inflorescences.
  • A familiar example of wind pollination is observed in corn, where the tassels represent the stigma and style that wave in the wind to trap pollen grains.
  • Grasses are a common example of plants that rely on wind pollination.
