Dispersal is the carrying of seeds, fruits or spores away from the parent plant. The carriers are few and ancient: the wind, animals, water — and some fruits that fling their seeds themselves.
Examples
Example 39.3 (Why leave home at all?)
A seed dropped at the parent’s foot germinates in the parent’s shade, among the parent’s roots — competing for the very light and water of Proposition 22.3 with a rival a hundred times its size. Dispersal is the escape from that losing match: distance is the first gift a plant gives its young.
