Trichome
Trichomes ( or ), from the Greek τρίχωμα (trikhōma) meaning "hair", are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. == Algal trichomes == Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as Spirulina and Oscillatoria. Cyanobacteria trichomes may be unsheathed, as in Oscillatoria, or sheathed, as in Calothrix.〔(【引用サイトリンク】title=Identify That Alga )〕 These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure.
