Fruit, a new book by Rob Kesseler and Wolfgang Stuppy, provides an amazingly up close examination of the colourful fruits and seeds that make our world so tasty. Kesseler and Stuppy use electron microscopy to showcase seeds, sometimes providing insight into the ingenious ways in which fruits make sure their seeds get spread. The photos are beautiful.
Scarlet pimpernel. When an animal brushes past the scarlet pimpernell, it knocks the outer casing open so that the seeds can escape. Seeds that fall onto the animal catch a free ride to distant fields.
Creeping carrot. This seed has wings, which allow it to fly in the wind, and spikes, which allow it to attach to passing animals. In either case, it can go far.
Poppy. When the wind blows the poppy, its tiny little seeds are thrown out of the open holes at the top of the capsule, like salt from salt shaker.
Three corner jack (Emex australis). Now matter how this seed falls, it always has a sharp spike that will stick up into the air, so that it can lodge itself into the foot of a passing animal and hitch a ride.
