Secondary Thickening Encyclopedia
secondary thickening (secondary growth) The formation of new tissue by the repeated lateral division of cells in the cambium of a woody plant, adding successive layers of new growth This increases the girth of the stem or root, and the growth can be seen as annual rings (treerings)secondary growth (secondary thickening) The increase in thickness of plant shoots and roots through the activities of the vascular cambium and cork cambium It is seen in most dicotyledons and gymnosperms but not in monocotyledonsSecondary Growth EncyclopediaSecondary growth occurs in many roots and usually results in the thickening of the root diameter by the addition ofvascular tissue Initiation of secondary growth occurs when cells in the residual procambium and parts of the pericyle begin to make periclinal divisionsSecondary Growth in Roots University of California, DavisThe thickening of the stem that occurs in secondary growth is due to the formation of secondary phloem and secondary xylem by the vascular cambium, plus the action of cork cambium, which forms the tough outermost layer of the stem The cells of the secondary xylem contain lignin, which provides hardiness and strength302C: Primary and Secondary Growth in Stems Biology Secondary growth involves the thickening of the plant axis through the activity of lateral meristems The end result of secondary growth is increased amounts of vascular tissue As plants grow larger, more vascular tissue is needed for water conduction and the transport of nutrientsStem Secondary Growth Why?
Secondary Growth in Monocotyledonous Stem Plants
Dec 12, 2016 Diffuse secondary thickening: In palm stem the ground parenchyma cells, close to and distant from the shoot apex (ex Roystonea, Actinophloeus etc), expand along with proportional increase of the intercellular spaces, thus causing diffuse secondary growthThe thickening of the stem that occurs in secondary growth is due to the formation of secondary phloem and secondary xylem by the vascular cambium, plus the action of cork cambium, which forms the tough outermost layer of the stem The cells of the secondary xylem contain lignin, which provides hardiness and strengthStem Growth Biology for Majors IIsecondary growth (secondary thickening) The increase in thickness of plant shoots and roots through the activities of the vascular cambium and cork cambiumIt is seen in most dicotyledons and gymnosperms but not in monocotyledons The tissues produced by secondary growth are called secondary tissues and the resultant plant or plant part is the secondary plant bodySecondary Growth Encyclopediasecondary thickening or secondary growth the growth in the girth of stems and roots in DICOTYLEDONS produced by division of the secondary MERISTEM, resulting in woody tissues The growth begins by the formation of a continuous cambial ring In stems there is already a fascicular cambium between the xylem and phloem of the vascular bundles which Secondary thickening definition of secondary thickening Secondary growth Ø As we discussed in the previous post about the anomalous secondary growth in Bougainvillea stem, here in Boerhavia also, the secondary thickening occurs by the formation of successive rings of accessory cambia Ø After the primary growth, the vascular bundles of middle ring increase in thickens to a limited extend b the activity of their fascicular cambiumBoerhavia Anomalous Secondary Growth Easy Biology Class

Increase in lateral thickening is called as secondary thickening or secondary growth Inter and intrafascicular cambiums join to form a complete ring of cambium called as vascular cambium The vascular cambial cells are the meristematic cells that continuously divide into daughter cells This development takes place in stele (intrastellar secondary growth) and also in cortex (extra stellar The thickening of the stem that occurs in secondary growth is due to the formation of secondary phloem and secondary xylem by the vascular cambium, plus the action of cork cambium, which forms the tough outermost layer of the stem The cells of the secondary xylem contain lignin, which provides hardiness and strengthPlant Growth Biology for Majors IIthe thickening ring (Scott Brebner, 1893), the Etagencambium (Schoute, 1902), the meristematic zone (Arber, 1925), the secondary thickening meristem (Clowes, 1961), the anomalous cambium (Stone, 1970), the vascular cambium (Zimmermann Tomlinson, 1970, 1972), the accessory cambium (Rastogi, 2009), the cambiumlike zone (Beck, 2010) and the monocot cambium (Carlquist, 2012), as well as (b Secondary thickening Article about secondary thickening Jul 24, 2015 For more information:7activestudioinfo@7activestudio7activemedical/info@7activemedicalsciencetuts/7activSECONDARY GROWTH YouTubePrimary growth of some roots is followed by secondary growth involving formation of secondary vascular tissues by the cambium and of periderm by a phellogen (cork cambium) Secondary thickening may start during the first or second year Stages in formation of the cambium and secondary growth of a woody root are shown in Fig 328 At first some Cork Cambium an overview ScienceDirect Topics
