Plant seeds can be divided into two basic types. Some are babies that plants actually want predators to eat. These seeds are encased in a hard coating designed to survive a trip all the way through the predator’s GI tract, although a large baby, such as a peach seed, might not be swallowed, and instead simply be left behind. Then there are “naked babies,” which lack such a protective coating; the plant does not want these to be eaten (more on them shortly).
