Some plants are able to survive in extreme conditions due to their evolutionary adaptations. These plants have developed unique features that help them thrive in harsh environments, such as deserts or high altitudes. Some of these adaptations include deep root systems to access water, thick waxy coatings to reduce water loss, and the ability to store water or nutrients for long periods of time. Additionally, certain plants have mechanisms to tolerate extreme temperatures, high salinity, or low nutrient levels, allowing them to survive in challenging conditions where other plants may struggle to grow.
