To identify and illustrate the anthers and stigmas of a wind-pollinated flower, we can focus on the key characteristics and structures that facilitate this type of pollination.

Key Features of Wind-Pollinated Flowers

1. Anthers:
   • Wind-pollinated flowers typically have long, protruding anthers that are well-exposed to the air. This design allows for easy dispersal of pollen grains into the wind.
   • The anthers produce a large quantity of lightweight, smooth pollen grains that can be carried by air currents.
2. Stigmas:
   • The stigmas of wind-pollinated flowers are often large and feathery, which increases their surface area to effectively catch airborne pollen grains.
   • These stigmas are usually positioned outside the flower to maximize exposure to the wind.

Summary of Functions

• Anthers: Produce and release pollen grains; designed to be easily dislodged by wind.
• Stigmas: Capture pollen grains from the air; feathery structure enhances efficiency in trapping pollen.
