How do plants adapt to drought conditions?

📌 CONCEPT: Plants adapt to drought conditions by conserving water through various morphological and physiological modifications.

📐 RULE / FORMULA: The key adaptations include developing a deep root system, reducing leaf size, and increasing leaf waxy coating to minimize water loss.

💡 WORKED EXAMPLE: The Acacia tree is an example of a plant that has developed a deep root system to access water deep in the soil, and its small and waxy leaves minimize water loss. Other adaptations include succulent plants like cacti that store water in their stems and leaves, and plants that have a low rate of transpiration like the Aloe vera.

⚠️ COMMON MISTAKE: Students often overlook the importance of morphological adaptations in plants to conserve water, and instead focus only on physiological adaptations like drought-resistant genes.
