	A '''~~trichome~~''' ~~is a small hair~~ or ~~other outgrowth from the epidermis of a plant~~. ~~Trichomes~~ are found on ~~a wide variety of plant species and serve various functions~~, ~~including protection against herbivory~~, ~~reduction of water loss~~, and ~~trapping~~ of ~~insects~~.		[[File:Cap1033-botao1.jpg\|Trichomes on a plant bud\|thumb\|right]]

			'''Trichomes''' are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are highly variable in form and function and can be found on the stems, leaves, flowers, and fruits of plants. Trichomes can be unicellular or multicellular and may be glandular or non-glandular.

	* '''Glandular trichomes~~''': These trichomes secrete substances such as essential oils, resins,~~ or ~~other compounds~~. ~~They are often found on plants like [[Cannabis]] and~~ [[Drosera]].		=== Non-Glandular Trichomes ===

			Non-glandular trichomes are primarily involved in protecting the plant from herbivores and environmental stress. They can be simple hairs or more complex structures.

			=== Glandular Trichomes ===

	* '''Non-glandular trichomes~~''': These are simple hair-like structures that do not~~ secrete substances. ~~They~~ can ~~be found~~ on ~~plants like~~ [[~~Arabidopsis thaliana~~]] ~~and [[Solanum]] species~~.		Glandular trichomes secrete substances such as oils, resins, or mucilage. These secretions can deter herbivores, attract pollinators, or reduce water loss. For example, the glandular trichomes on the leaves of the carnivorous plant ''[[Drosera capensis]]'' secrete a sticky substance to trap insects.

	== Functions ==		== Functions of Trichomes ==

	Trichomes serve ~~multiple~~ functions ~~in plants~~:		Trichomes serve various functions depending on their type and location:

	* '''Protection''': Trichomes can ~~deter~~ herbivores by making the plant surface less palatable or more difficult to consume.		* '''Protection''': Trichomes can protect plants from herbivores by making the plant surface less palatable or more difficult to consume.
			* '''Temperature Regulation''': They can help in regulating temperature by reflecting sunlight and reducing water loss through transpiration.
			* '''Secretion''': Glandular trichomes can secrete substances that deter herbivores or attract pollinators.
			* '''Physical Barrier''': They can act as a physical barrier against pathogens and insects.

	* '''Water conservation''': By reducing air flow over the plant surface, trichomes can help reduce water loss through evaporation.		== Trichomes in Different Plants ==

	* '''Light reflection''': ~~Some~~ trichomes ~~reflect sunlight, reducing leaf temperature and protecting against UV radiation.~~		[[File:Trichomes_Close_Cannabis.jpg\|Close-up of cannabis trichomes\|thumb\|right]]

	* '''Insect trapping''': In carnivorous plants ~~like [[Drosera]]~~, ~~trichomes can trap insects, which are then digested by~~ the plant.		Trichomes are found in a wide variety of plants, each adapted to the specific needs of the plant:

	~~== Examples ==~~		* '''Cannabis''': The trichomes on cannabis plants are known for producing cannabinoids, which have psychoactive and medicinal properties.
			* '''''[[Solanum scabrum]]''''': This plant has trichomes on its leaf lamina that can deter herbivores.
			* '''''[[Solanum quitoense]]''''': The petiole of this plant is covered with trichomes that may protect it from pests.

	* '''[[Cannabis]]''': The trichomes on cannabis plants are glandular and produce the plant's psychoactive compounds.		== Fossilized Trichomes ==

	* '''[[~~Drosera capensis~~]]~~''': This carnivorous plant uses glandular trichomes to trap and digest insects.~~		[[File:Sternhaar_in_Baltischem_Bernstein.jpg\|Trichomes preserved in amber\|thumb\|left]]

	* '''[[Solanum quitoense]]''': This plant has non-glandular trichomes ~~that~~ provide ~~a protective barrier~~.		Trichomes can also be found in the fossil record, preserved in substances like amber. These fossilized trichomes provide valuable information about ancient plant life and the environments in which they lived.

==Functions of Trichomes==
Trichomes serve several important functions in plants, including:

* '''[[Defense Mechanism|Defense]]''': Trichomes can deter or harm insects and other animals that try to eat the plant.

* '''[[Temperature Regulation]]''': By reflecting sunlight, trichomes can help to keep the plant cool in hot conditions.

* '''[[Moisture Regulation]]''': Trichomes can reduce the rate of water loss from the plant, helping it to conserve moisture.

==Trichomes in Cannabis==
In [[Cannabis]], trichomes are particularly important as they produce the plant's cannabinoids, including [[THC]] and [[CBD]]. These compounds have a variety of medicinal and recreational uses.
