Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. [5] Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the Golgi apparatus. [6]
The adjective, pectinate, means supplied with a comb-like structure. This form, cognate to pecten with both derived from the Latin for comb, pectin (genitive pectinis), is reflected in numerous scientific names in forms such as pectinata, pectinatus or pectinatum, or in specific epithets such as Murex pecten.
Cell wall and middle lamella (top). The middle lamella is a layer that cements together the primary cell walls of two adjoining plant cells.It is the first formed layer to be deposited at the time of cytokinesis. [1]
This story is a component of the feature “Seasons of Preserves: Citrus Marmalade,” which is part of a four-part series on preserving fruit at home called “L.A. in a Jar.” If you know even ...
It is useful because pectin is the jelly-like matrix which helps cement plant cells together and in which other cell wall components, such as cellulose fibrils, are embedded. Therefore, pectinase enzymes are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juice from fruit ...
Pecten (biology), any comb like structure in animals; Pecten, a genus of scallops; Pecten (company), a subsidiary of Sinopec; Pecten oculi, a structure in the bird retina which contains most of the vasculature
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
The stem of a plant, especially a woody one; also used to mean a rootstock, or particularly a basal stem structure or storage organ from which new growth arises. Compare lignotuber. caudiciform Stem-like or caudex-like; sometimes used to mean "pachycaul", meaning "thick-stemmed". caudicle diminutive of caudex.
