support: Many plants respond to the days growing shorter in the fall by going dormant. They suspend growth and development in order to survive the extreme coldness and dryness of winter. Part of this response causes the leaves of many trees to change color and then fall off (see Figure below ). Dormancy ensures that plants will grow and produce seeds only when conditions are favorable.
