Which mechanism allows xerophytes to conserve water when soil moisture declines under drought conditions?

💡 Explanation

Drought stress causes abscisic acid (ABA) production, triggering stomatal closure. ABA induces the mechanism of stomatal closure by reducing guard cell turgor, because this reduces transpiration, therefore conserving water, rather than futilely optimizing cytokinin production under adverse conditions.
