Fruit Types and Seed Dispersal
Captions available
The idea
A fruit's structure matches its dispersal strategy: fleshy fruits attract animals that eat and excrete seeds elsewhere; dry fruits disperse by wind.
In practice
A cherry's flesh rewards an animal that disperses its seed in droppings; a maple's winged fruit spins on wind.
Where people slip
A fruit's fleshiness signals dispersal strategy, not edibility — many fleshy fruits are toxic to some animals.
