later spits out the seeds somewhere far from its parent tree.

of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds
actually require passage through an animal’s body before they can grow. Wild strawberries offer a

planted, the surrounding fruit is green, sour, and hard.
