Plant trichomes can be classified in many ways, including by their shape, size, and function:
Glandular vs non-glandular: Glandular trichomes can synthesize and secrete specialized metabolites, such as terpenoids, phenylpropanoids, and flavonoids.
Single-celled vs multicellular: Trichomes can be made up of a single cell or multiple cells.
Branched vs unbranched: Trichomes can be branched or unbranched.
Capitate vs peltate: Capitate trichomes have a stalk that is more than half the height of the head, while peltate trichomes have a short stalk and a large secretory head.
Bulbous vs sessile vs stalked: Bulbous trichomes are small and low, sessile trichomes have a globular head on a short stalk, and stalked trichomes have a larger globular head on a long stalk.
Large vs small: Trichomes can be classified as large or small based on their distribution on the plant.
Head shape: Trichomes can have different head shapes, such as head, star, hook, and scale.
The morphology of trichomes can also be associated with the spatial distribution of plant organs. For example, the base of a tomato stem has long trichomes, while the upper parts of the stem have short and sparse trichomes.
