Describe adaptations in the structure of wind-pollinated and insect-pollinated flowers.

Small, Inconspicuous Flowers:
- Wind-pollinated flowers are usually small and lack bright colors or strong scents since they don’t rely on insects for attraction.
Light, Non-Sticky Pollen:
- The pollen is lightweight, smooth, and non-sticky, allowing it to be easily carried by the wind to other flowers.
Exposed Stamens and Pistils:
- The male parts (stamens) and female parts (pistils) are often large, extended, and exposed to catch wind-blown pollen.
Large, Feathery Styles and Stigmas:
- The stigma (female part) is large, feathery, or branched to catch pollen efficiently as it drifts through the air.
Abundant Pollen Production:
- Wind-pollinated plants produce large amounts of pollen to increase the chances of successful pollination.
No Need for Bright Colors:
- Since these plants don’t rely on attracting insects, they typically have dull-colored flowers.

Brightly Colored Flowers:
- Insect-pollinated flowers are often brightly colored (e.g., red, yellow, or blue) to attract pollinators.
Fragrant Scents:
- They produce strong, sweet scents to lure insects like bees, butterflies, or moths.
Nectar and Pollen:
- These flowers offer nectar as a reward for insects, and the pollen is sticky to adhere to the bodies of insects as they feed.
Larger and Showy Flowers:
- The flowers are usually larger and showier, with structures that are adapted to the visiting pollinators (e.g., long tubes for hummingbirds or flat platforms for bees).
Specialized Flower Shapes:
- Many insect-pollinated flowers have shapes that match the body of a specific pollinator, ensuring efficient pollen transfer (e.g., tubular flowers for long-tongued insects like bees or butterflies).
Protection of Reproductive Organs:
- The stamens and pistils are often positioned so that insects come into contact with them while feeding on nectar, promoting effective pollination.
