Trees do not have hair – trees have trichomes. Trees have many different types of thread-like growths on buds, leaves and roots, but none of them are hairs. Mammals have hair and fur. Trees have trichomes.
Take a close look at a sycamore leaf. It can be so fuzzy on its underside that the dense trichomes can be rubbed off into small balls of fluff. Sycamore leaf trichomes can cause allergic reactions and respiration problems. The fuzzy materials are not hairs but trichomes.
Animal hair come in two general forms, a set length and always growing. Both types of animal hairs grow from the bottom where they form within the skin of an animal. Trichomes are developed from the outer surface layers of cells.
