Xerophytic adaptation
nounPronunciation: /ˌzɪroʊˈfɪtɪk ədˈæptəʃən/
Structural and physiological modifications that enable plants to survive prolonged drought conditions by reducing water loss and optimizing water utilization. These adaptations include waxy leaf coatings, reduced stomatal density, and deep root systems.
Plain English
Physical changes plants make to survive in dry environments by minimizing water loss.
Etymology & History
Usage
"Xerophytic adaptations in creosote bush allow it to thrive in the Mojave Desert with minimal rainfall."

Frequently Asked Questions
What are common xerophytic adaptations in desert plants?
Common adaptations include thick waxy cuticles, reduced leaf area, sunken stomata, and extensive root systems for water capture.
How do xerophytes differ from mesophytes?
Xerophytes are specialized for arid environments with structural adaptations, while mesophytes are adapted to moderate water availability.
Why Test Candidates on This?
Frequently tested in plant physiology and abiotic stress exams to assess understanding of evolutionary plant strategies.
