Trichome 

in plants, an outgrowth of epidermal cells that varies in shape, structure, and function. (Deeper-lying tissues participate in the formation of emergences.) The most common trichomes are hairs and glumes. The long, soft hairs that cover cotton seeds are a valuable raw material for the textile industry. The structures of trichomes and their location on plant organs have taxonomic significance (for example, in the family Cruciferae).
