Examples of desert plants that need little water.

🌵 Quick Study Guide

• 💧 Adaptation is Key: Desert plants have evolved special adaptations to survive in arid conditions.
• ☀️ Water Storage: Many store water in their leaves, stems, or roots.
• 🍃 Reduced Leaf Surface: Some have small or no leaves to minimize water loss through transpiration.
• 🌵 Waxy Coatings: Waxy layers on stems and leaves help prevent evaporation.
• ⏰ Dormancy: Some plants become dormant during dry periods, conserving energy and water.
• 🧽 Extensive Root Systems: Many have extensive root systems to quickly absorb any available water.
• 🌡️ Tolerance to High Temperatures: Desert plants are adapted to withstand extreme heat.
