Why Might Leaves Have Thick Cuticle Layers. A primary function of the leaf’s waxy cuticle is to reduce water loss through the. While the past decade has seen unprecedented progress in the molecular biology of cuticle biogenesis, many studies have revealed.

Some water needs to evaporate from the leaf’s surface to keep water moving from the roots up through the plant’s internal plumbing (the xylem vessels). Plant cuticles protect the interior tissues from ambient hazards, including desiccation, uv light, physical wear, herbivores and pathogens. A primary function of the leaf’s waxy cuticle is to reduce water loss through the.

The cuticle is designed to keep water and solutes in, but to keep invaders out. On leaves, the cuticle is 1/10 to 14 micrometers thick. Also, based on the evidence of bueno et al., whatever the role of the cuticle, the main difference between plants grown in arid and moist environments was the thickness of the layer: A primary function of the leaf’s waxy cuticle is to reduce water loss through the.
