What is Dispersal?

Definition 39.2 Primary & Middle School Biology · Chapter 39 — How Plants Spread

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.
