A fine outgrowth, such as a hair or glandular stalk, from the epidermis of a plant.
Danh từ
Số nhiều: trichomes

This term is primarily used in botanical and biological contexts to describe specialized epidermal appendages. It carries a technical, scientific register and is rarely encountered in casual conversation unless discussing plant anatomy, agriculture, or pharmacology.

Because trichomes can be either simple hairs or complex glandular structures that secrete resins and oils, the word encompasses a wide range of biological functions, from defense against herbivores to the regulation of transpiration and temperature.
