How Leaves Repel Water: A Science Project Guide

A student asked how leaves repel water for a science project. The expert provided a Google search link for relevant articles.

Leaves repel water through microscopic surface structures (like wax crystals) and chemical coatings (cuticle) that create superhydrophobic surfaces, causing water to bead and roll off—a phenomenon known as the lotus effect. This self-cleaning property helps prevent fungal growth and maintains gas exchange.

For a project, explore terms like "leaf cuticle," "hydrophobicity," "lotus effect," and "epicuticular wax."
