Hairs and glands on thyme

False-colour scanning electron micrograph of the leaf surface of the herb thyme, Thymus vulgaris. The micrograph shows two types of trichomes (projections from the leaf surface); unbranched multicellular hairs (green), which cover most of the surface & glandular trichomes (red spheres), the source of the aromatic oil which gives the herb its value in cooking.
