Where are laticifers in plants?
A laticifer is a type of elongated secretory cell found in the leaves and/or stems of plants that produce latex and rubber as secondary metabolites.
What are articulated laticifers?
Articulated laticifers consist of an unbranched or branched series of cells, which are usually elongated. In this type of laticifer the end walls may become porous or undergo complete lysis (Fahn 1979).
What is Laticiferous cell?
Laticifer cells are specialized plant cells that synthesize and accumulate latex.
What are secretory duct?
Secretory ducts are internal glands composed of an epithelium formed by secretory cells that release the exudate in an elongated intercellular space called lumen [1].
What are latex cells?
Latex cells, although much branched like the latex vessels, are really single or independent units. They originate as minute structures and then, with the growth of the plant, elongate and branch, ramifying in all directions through the tissues of the plant, but without fusing together to form a network.
What are latex cells give an example?
latex, colloidal suspension, either the milky white liquid emulsion found in the cells of certain flowering plants such as the rubber tree (Hevea brasiliensis) or any of various manufactured water emulsions consisting of synthetic rubber or plastic.
What are non articulated laticifers?
Nonarticulated laticifers arise from a single cell in the embryo, a cell that elongates along with plant development and grows intrusively between other cells via tip growth. The cells undergo karyokinesis without cytokinesis, resulting in multinucleate (coenocytic) cells.
What is Lactifer?
A special cell, found in the bark of the rubber tree (Hevea), in which rubber latex accumulates. From: lactifer in Oxford Dictionary of Biochemistry and Molecular Biology » Subjects: Science and technology — Chemistry.
What is the difference between articulated and non articulated laticifers?
Basically, nonarticulated laticifers (e.g., in Euphorbia lathyris) assemble a network that is essentially a single cell permeating the entire plant body while articulated laticifers (e.g., in Hevea brasiliensis) are a series of interconnected individual cells.
What is non articulated laticifers?
This spurge stem shows a common type of laticifer called a non-articulated laticifer. The word “non-articulated” means that it is all one long cell rather than a series of cells joined together (the vessels of xylem are articulated structures made up of many cells, the vessel elements).
What is duct in plants?
Resin ducts are canals lined with secretory cells that release resins into the canal. Resin ducts are common in gymnosperms and occur in various tissues of roots, stems, leaves, and reproductive structures. Gum ducts are similar to resin ducts and may contain resins, oils, and gums.
What is called latex?
Latex is a stable dispersion (emulsion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. Latex as found in nature is a milky fluid found in 10% of all flowering plants (angiosperms).
