Resin canal

A resin canal is a structural feature found in some plants, particularly conifers, that allows for the storage and transportation of resin. Resin is a sticky, viscous substance produced by certain trees, primarily for defensive purposes, as it can deter herbivores and protect against pathogens. The resin canal itself is often a tube-like structure that runs through the plant's tissues, specifically within the xylem or phloem.
