The Debate on Helical Thickenings

Researcher 1: The presence of helical thickenings in tracheids of certain conifers enhances hydraulic efficiency by maintaining water flow under tension. This adaptation is critical for species growing in drought-prone regions.

Researcher 2: While helical thickenings may contribute to hydraulic efficiency, their primary function is to provide structural support to tracheids, preventing collapse under mechanical stress. They are not necessarily linked to adaptations for drought conditions.

Researcher 1 and Researcher 2 disagree over;
