What is the protective structure of oregano?

The protective structure of oregano is called trichomes. Trichomes are small, hair-like structures that cover the surface of oregano leaves and stems. They are composed of a variety of chemicals, including terpenes and flavonoids, which give oregano its characteristic flavor and aroma. Trichomes also play an important role in protecting the plant from pests and diseases. By secreting a sticky resin, trichomes trap insects and other small pests. They also help to deter larger animals from eating the plant by creating a physical barrier. In addition, trichomes can produce antimicrobial and antifungal compounds that help to protect the plant from infection.
