Trichomes are minute highly specialized outgrowths that are found along any surface of a plant and are designed to enhance a plant's chances of survival. These accessory structures occur most often along stems and leaves but can also be found on the surface of petals and also comprise the fragrant and sweet necturaries that draw pollinating creatures. Many forms of trichome help adjust the microclimate on the surfaces of the leaves by reflecting solar radiation and prevent evaporation of critical water supplies. Trichomes that manifest curly shapes are developed for use as reflectors by such plants as the desert brittlebush. Each variety of plant produces trichomes that are most suited to cope with the conditions of its environment. Although various forms exist, these appendages commonly occur as glandular, nonglandular, scales, papillae, or hair-like structures.
