"Key fruit" is an informal term often used to describe a samara, which is a dry, indehiscent fruit with a wing-like structure. Think of maple or ash tree seeds that spin when they fall. 🍁 The "key" refers to the shape resembling old-fashioned keys. The wing shape aids in wind dispersal, allowing the seed to travel far. It's a handy way for trees to spread their offspring. So, a key fruit is simply a seed with a built-in glider.
