TWO ADVANTAGES ARE
(1) Clothes the Leaf
The cuticle is a multi-layer structure composed primarily of cutin, cutan, polysaccharides, lipids and waxes. On the inward-facing side of a leaf, the cuticle attaches to the epidermal plant cell walls, and on the outward-facing side, the cuticle forms a film or skin that covers the leaf surface. Cutin forms an insoluble hydrophobic barrier, which means it does not disintegrate by dissolving in water but remains in place to protect the leaves. Cuticle thickness varies, depending on plant type and the plant parts it covers. On leaves, the cuticle is 1/10 to 14 micrometers thick.
(2) Reduces Water Loss
A primary function of the leaf’s waxy cuticle is to reduce water loss through the leaves, which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall. Plants such as Adam’s needle (Yucca filamentosa), which grows in U.S. Department of Agriculture plant hardiness zones 5 through 10, use the cuticle in tandem with their stomata to conserve water. Stomata are pores on the leaf surfaces that open and close to regulate water and gas exchange. Yucca opens its stomata at night to receive carbon dioxide for photosynthesis and it closes its stomata during the day to reduce water loss through transpiration. The cuticle helps seal in the water, making the leaves virtually waterproof
