👉 Trichomes are a type of epidermal hair cell, typically found in the skin or on the surface of various plant and animal tissues. They are responsible for producing a variety of pigments, including melanin, which is essential for regulating body temperature, as well as other pigments such as chlorophyll, which helps to absorb light energy from the sun. Trichomes also have the ability to produce hormones that regulate the growth and development of various tissues in the body.
