DENDROLOGY

Detailed explanation-1: -A plant cuticle is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm. It consists of lipid and hydrocarbon polymers impregnated with wax and is synthesized exclusively by the epidermal cells. So, the correct option is D. ( Leaf and stem both )

Detailed explanation-2: -Abstract. The plant cuticle is an extracellular hydrophobic layer that covers the aerial epidermis of all land plants, providing protection against desiccation and external environmental stresses.

Detailed explanation-3: -A cuticle is a non-cellular waxy layer secreted by epidermal cells. Its water-resistant nature helps in reducing the loss of water. Cuticle is very beneficial for desert plants as they require to conserve water and not loose it during transpiration.

Detailed explanation-4: -A cuticle is a hydrophobic boundary layer on the outer surface of primary aerial organs. Its presence is a common feature of all vascular and some non-vascular plants. Attaining the capacity to form such a boundary layer was critical to the evolutionary success of early terrestrial plants [1, 2].

Detailed explanation-5: -A cuticle is a non-cellular waxy layer secreted by epidermal cells. It protects the epidermis and reduces water loss.
