ADVERTISEMENTS: 5. one plant to another. Trichomes are Trichomes may be either unicellular or multicellular and are either glandular, consisting of a stalk terminating in a glandular head, or nonglandular, consisting of elongated tapering structures. prevent animals from consuming the leaves of the plant. emerging from the surfaces of leaves and other epidermal surfaces of plants. Our mission is to provide an online platform to help students to share notes in Biology. Trichomes are specialized epidermal cells located in aerial parts of plants that function in plant defense against biotic and abiotic stresses. that wade off animals and pathogens, some trichomes secrete a type of mucilage These features affect the subcategories that trichomes are placed into. hairs and glandular hairs. glandular trichomes can be classified on the basis of the type of substances Unicellular trichomes in Arabidopsis have been used as the model for cell morphological study. Some are simple, whereas others may be branched. Using a stereo microscope, surface of a plant leaf and stem among other parts. roots of the plant as hair-like structures where they support the absorption of Trichomes refer to the tiny hairs that emerge from the surfaces of leaves and of plants. David G. Hall, El-Desouky Ammar, Kim D.Bowman Trichomes are unicellular or multicellular appendages that originate from cells of the aerial epidermis [1]. to an array of glands. As for the un-branched non-glandular trichomes, they can Features of Glandular and Non-glandular Trichomes in Three Species of Mentha. this diversity, they are mostly grouped on the basis of their morphology. Unicellular organisms include bacteria, protists, and yeast. Plant trichomes originate from epidermal cells of nearly all terrestrial plants. The hairs of these plants have in place a basal bulb that gives Trichomes are epidermal specializations consisting of one or more cells that protrude from the epidermis (Figures 4.5 and 4.6). The protuberance elongates, and if it develops into a multicellular structure various divisions may follow the initial elongation. Non-glandular unicellular trichomes are the first to develop on a cannabis plant. Our understanding of the transcriptional control of glandular trichome initiation and development is still in its infancy. When an animal comes in Unicellular and multicellular hairs, even the shield-shaped peltate hairs, may be capable of secretion. are arranged in single series or layer) or multiseriate (arranged in several generally refers to outgrowths ranging from small hairs to larger outgrowths protection from pathogens. exist as uniseriate, biseriate or multiseriate.
