Trichomes are tiny, hair-like structures found on the surface of many plants, including cannabis and roses. They serve various functions, such as protecting the plant from herbivores and environmental stress. Trichomes can produce and store essential oils, resins, and other compounds that contribute to a plant's aroma and flavor. These structures come in different shapes and sizes, including glandular and non-glandular types. Glandular trichomes are particularly important because they produce cannabinoids and terpenes, which are key components in the medicinal and recreational properties of cannabis. Non-glandular trichomes may help with water retention and temperature regulation.
