Trichomes serve a number of functions, which include physical and chemical protection for the leaf against microbial organisms, aphids and insects, and the maintenance of a layer of still air on the leaf surface, thus combating excess water loss by transpiration.

What purpose do trichomes serve in most plants?
Glandular trichomes, epidermal appendages found on the stems and leaves of many plants, store and secrete secondary metabolites in a species- and cultivar-specific fashion. The accumulation of these toxic compounds at the plant's surface may provide a first line of defense against insects, pathogens, and herbivores.
What are the benefits of trichomes?
Trichomes deter them and predators by giving the plant a strong aroma and bitter taste. They also protect cannabis plants from environmental stressors like harmful UV rays and the wind. Glandular trichomes produce terpenes that pests find unpalatable, while non-glandular ones trap and impale tiny insects.
What do trichomes produce?
Trichomes, on the other hand, are found on the portions of the plant that are above ground, mostly on buds and sugar leaves. They secrete terpenes and cannabinoids that provide pest and disease protection for plants. Small bulbous trichome glands can even trap and confine tiny insects.
What is the function of trichomes '? 1 point?
Protection and reduction of transpiration.
How do trichomes help in taxonomy?
Trichomes are distributed at the surface of aerial plant parts, having various functions and are extremely variable in their presence across plant, location on plant organs, density, form, etc., and, therefore, their morphology and structure can be used as taxonomic markers in the infrageneric classification of the ...
How do trichomes reduce water loss?
Trichomes in general are features of xerophytic leaves, which reduce water loss by evaporation by trapping water vapor and increasing humidity (as a result lowering the water potential gradient).
Do all plants have trichomes?
Glandular trichomes have been vastly studied, even though they are only found on about 30% of plants. Their function is to secrete metabolites for the plant.
What are trichomes in reference to plants?
Trichomes are defined as unicellular or multicellular appendages, which are an extension of the above-ground epidermal cells in plants [1]. These appendages play a key role in the development of plantsand occur in a wide variety of species [2].
How trichomes are formed?
Trichome formation is promoted by the activating protein complex containing three groups of transcription factors: the R2R3 MYB, basic helix-loop-helix, and WD40 repeat proteins. ... In addition, phytohormones are involved in trichome formation, including GA as a promoter of trichome initiation (Chien and Sussex, 1996).
What are the stages of trichomes?
There are essentially four stages of trichome development, as shown above: Clear, Cloudy, Amber and Mixed. Each of these stages have various consequences on the strain effects, and can be great indicators of when to harvest.
What are amber trichomes?
When trichomes are all ranging in color from amber to brown, this is when the plant has reached its full maturity. If you are growing cannabis solely for THC content, you must act quickly—once the trichomes turn amber, they start to degrade in quality.
What are pistils and trichomes?
Trichomes and pistils are completely different parts of the cannabis plant, but it's easy to see why people sometimes confuse them. ... Then, trichomes create and store cannabinoids and terpenes, while pistils (which are only present on female cannabis plants) serve to receive pollen from male cannabis plants.
