A plant species adapted to waterlogged conditions exhibits aerenchyma formation in its roots. Which of the following BEST explains the adaptive advantage of this anatomical modification?
Increases root surface area for enhanced water absorption
Provides structural support to prevent root collapse in saturated soil
Facilitates oxygen transport to submerged root tissues, enabling aerobic respiration
Stores excess water for use during periods of drought
