Natures fortress How cacti keep water in and predators out
Cacti have evolved various adaptations to survive in harsh desert climates. Their spines serve multiple functions, including reducing water loss, shading the plant, and acting as an insulating layer. Cacti also have thick skin and specialized root systems that allow them to store water and quickly take up available water after rainfall. These adaptations enable cacti to thrive in a range of environments, from the driest desert to the tropical rainforest.
