Answered step-by-step

The structures and pollen characteristics of insect-pollinated and wind-pollinated flowers differ significantly due to their distinct reproductive strategies. Below is a comparison of these two types of flowers based on their flower structure and pollen features.

Comparison of Flower Structure

Feature Insect-Pollinated Flowers Wind-Pollinated Flowers
Petals Large, brightly colored to attract insects Small, dull, often green or brown
Scent and Nectar Present; sweet-smelling nectar attracts insects Absent; no need to attract pollinators
Anthers Located inside the flower; stiff and firmly attached to brush against insects Hanging outside the flower on long filaments for easy pollen release
Stigma Sticky, located inside the flower to catch pollen from visiting insects Feathery and large, positioned outside to catch airborne pollen
Pollen Quantity Moderate amount produced; efficient transfer by insects Large quantities produced; most are not transferred, so higher production increases chances of successful pollination

Comparison of Pollen Characteristics

Feature Insect-Pollinated Pollen Wind-Pollinated Pollen
Size Larger, often sticky or spiky Smaller, smooth, and lightweight
Shape Irregular shapes with spikes/hooks for adhesion Generally round or oval, designed for wind dispersal
Quantity Moderate quantity; sufficient for insect transfer Very high quantity; compensates for low transfer rates
