Final answer:
Drought resistance mechanisms in plants include escape, avoidance, and tolerance.
Step-by-step explanation:
The drought resistance mechanisms in plants include:
- Escape: Some plants have the ability to complete their life cycle before the onset of drought. For example, they may flower and produce seeds during a short rainy period before the drought begins.
- Avoidance: Plants can avoid drought conditions by growing in areas with high humidity, where droughts are uncommon.
- Tolerance: Drought-tolerant plants have adaptations that allow them to withstand and survive prolonged periods of drought. These adaptations include reducing water loss through features such as waxy cuticles, having deep root systems to access water deep underground, and adjusting their metabolism and growth as a response to water scarcity.
- All of the above: The drought resistance mechanisms mentioned above (escape, avoidance, and tolerance) are strategies employed by different plant species to survive and thrive in drought conditions.
