Xeric adaptation
nounPronunciation: /ˈzɛrɪk ədˈæpteɪʃən/
Evolutionary morphological and physiological modifications enabling plants to survive and grow in arid or drought-prone environments with limited water availability. These adaptations include reduced leaf area, altered root systems, and waxy cuticles.
Plain English
Physical and biological features that allow plants to survive in dry environments.
Etymology & History
Usage
"Desert plant species display remarkable xeric adaptations including deep root systems and succulent tissue storage."
Style guide notes: Use 'xeric adaptation' for evolutionary context; prefer 'drought tolerance' for short-term stress responses.

Frequently Asked Questions
What are common xeric adaptations in plants?
Reduced leaf area, waxy cuticles, deeper roots, succulent tissues, and stomatal reduction minimize water loss.
How do xeric adaptations develop evolutionarily?
Prolonged environmental selection pressure in dry habitats favors genotypes with water-conservation traits.
Why Test Candidates on This?
Important for understanding long-term evolutionary plant responses to chronic abiotic stress in arid regions.
