Difficulty: EasyExplicit Details

The resurrection plant (*Selaginella lepidophylla*) is a desert dweller renowned for its ability to survive extreme dehydration. During prolonged dry spells, the plant curls its stems into a tight, brown ball, entering a dormant state that minimizes water loss. When exposed to moisture, the stems uncurl and regain their green color, a process that can occur in as little as three hours. However, this rehydration is purely mechanical; the plant does not resume active growth until its root system is fully re-established in moist soil.
