How Seeds Survive Extreme Seasonal Drought

How does a seed plant survive when rain falls only during one short season and water is deep underground?

Seed Quiescence: Evolution's Survival Strategy

Seeds are evolutionary marvels. Each contains a living embryo (root + leaves) that enters quiescence—a state of suspended animation—as the seed matures and dries. Quiescent seeds wait for suitable conditions: warmth, moisture, oxygen. Most mature in late summer/fall but won't germinate until spring's warmth and rain. This timing prevents fall germination followed by winter kill. The seed coat protects the embryo until environmental cues signal it's safe to grow.
