Drought tolerance refers to the ability of plants to survive and thrive in conditions with limited water availability. This characteristic allows them to withstand periods of low rainfall or dry soil, helping them maintain growth and reproduction despite challenging environmental conditions. Plants exhibit drought tolerance through various adaptations, such as deep root systems, reduced leaf size, or the ability to store water. These traits enable them to minimize water loss and maximize water uptake, ensuring their survival in arid regions or during dry seasons. Examples of drought-tolerant plants include cacti, succulents, and certain types of grasses.
