When Do Resins Normally Be Found in Plants?

Resins are produced in special resin cells in plants, and are also produced when an injury occurs to the plant. Resins can be produced through the bark of a tree, the flowers of an herb, or the buds of a shrub. Think of a pine tree that has a missing tree limb.

Why do plants produce resin?

Plants secrete resins for their protective benefits in response to injury. The resin protects the plant from insects and pathogens.

In which group of plants does resin occur?

Most resin used commercially comes from trees of the Pinaceae, legume families, and Dipterocarpaceae. Copals are a group of resins extracted from leguminous forest trees and are known for their hardness and high melting point. Trees of the Dipterocarpaceae produce a resin called dammar in commerce.
