DENDROLOGY

Detailed explanation-1: -The plant cuticle, a cutin matrix embedded with and covered by wax, seals the aerial organ’s surface to protect the plant against uncontrolled water loss. The cutin matrix is essential for the cuticle to function as a barrier to water loss.

Detailed explanation-2: -Plant cuticle is the outermost layer of plants, which covers leaves, fruits, flowers, and non-woody stems of higher plants. It protects plants against drought, extreme temperatures, UV radiation, chemical attack, mechanical injuries, and pathogen/pest infection.

Detailed explanation-3: -The cuticle limits transpiration through plant surfaces other than through the stomatal pores to less than 10% of the total, 2 in exchange for strongly restricted CO2 uptake efficiency.
