Wind-dispersed seeds have lightweight structures for aerial travel

Steps:

• Examine fruit structures for adaptations to dispersal methods.
• Identify wind-dispersed fruits by features like wings, plumes, or thin membranes that aid floating on air currents.
• Compare options: A shows winged samara, B has barbs, C is fleshy berry, D is buoyant drupe.
• Select the one matching wind adaptation.

Why A is correct:

• Winged fruits like maple samaras use aerodynamic structures to spin and glide on wind, per plant dispersal biology.

Why the others are wrong:

• B: Hooks attach to animal fur for dispersal by movement.
• C: Fleshy exterior attracts animals to eat and excrete seeds.
• D: Waterproof husk enables floating on water currents.

Final answer: A
