Hydrophobic plants
Web17 nov. 2024 · Hydrophobic materials repel water. The main function of the waxy cuticle is to prevent water movement into or out of the leaf. It is important to prevent water loss from the plant as the water contained in the plant leaves is essential for photosynthesis to continue. Photosynthesis is how plants convert sunlight into energy. The high surface tension of water causes droplets to assume a nearly spherical shape, since a sphere has minimal surface area, and this shape therefore minimizes the solid-liquid surface energy. On contact of liquid with a surface, adhesion forces result in wetting of the surface. Either complete or incomplete wetting may occur depending on the structure of the surface and the fluid tension of the droplet. The cause of self-cleaning properties is the hydrophobic water-repellent d…
