All of these structures and features are present in pine needles (leaves). Resin canals are present in the needles to produce and store resin as a defense mechanism against herbivores and pathogens. A hypodermis is present in the needles to provide support and structure. Pine needles have a thick cuticle to reduce water loss and protect against environmental stresses. Sunken stomata are also present to reduce water loss and prevent desiccation.
