Secondary growth occurs in most seed plants but monocots usually lack secondary growth If they do have secondary growth it differs from the typical pattern of other seed plants The formation of secondary vascular tissues from the cambium is a characteristic feature of dicotyledons and gymnosperms In certain monocots the vascular tissues
read the restAlthough the increase in organ girth driven by a bifacial vascular cambium may be the common ancestral state the process of secondary growth has been clearly reshaped in different plant lineages Gymnosperms are predominantly woody plants whereas angiosperms encompass primary woody species derived herbaceous species and species which reacquired the capacity for secondary
read the restSecondary Growth Primary growth causes the plant to grow in length both below and above the ground due to the apical meristems that are actively dividing into these regions Secondary growth causes the plant to grow in width due to the presence of lateral meristems or cambium layer which actively divides to bring about this kind of growth

read the restThe primary growth is the initial process that develops the plant from a seedling into a fully mature plant The secondary growth which in a sense develops the leafy body of a plant may occur during or after the primary growth For example a vine begins to send out leafless shoots which is the primary growth

read the restPrimary and Secondary Growth The mitotic divisions in meristematic cells at the root and shoot apex hikes the length of the plant This is called as Primary Growth while Secondary meristem which results in an increased diameter of the plant known as Secondary Growth
read the restSecondary growth begins with the initiation of the vascular cambium a cylinder of meristematic tissue that produces additional xylic and phloic tissues The cells that eventually form the vascular cambium come from two sources the procambium in the vascular bundles and the interfascicular parenchyma cells between vascular bundles
read the restThese plants undergo processes of secondary growth superimposed on a continuing primary growth Apart from comparatively enormous increases in stem and root girth the largescale result of secondary growths is the development of bark and of wood
read the restGrowth of Plants Vascular cambium produces secondary xylem toward the center of the stem or root and phloem toward the outside of the stem or root adding growth to the diameter of the plant This process produces wood and builds the sturdy trunks of trees Cork cambium lies between the epidermis and the phloem

read the restSecondary Growth Plants Most commonly monocots dicots and gymnosperm plants will develop the secondary growth traits found in plants It is important to understand that although both are considered angiosperms or plants that fruit dicotyledon trees grow their secondary cells at a much faster larger rate than their monocotyledon counterparts

read the restSecondary growth is initiated by the activity of the vascular cambium as far as the steler region is intrafascicular cambium is absent in the open vascular bundles of the monocot stem thus the process cannot take place As for the roots dicots as well as monocots have closed vascular bundles
read the restOn the initiation of secondary growth a few parenchyma cells beneath each group of phloem become meristematic and thus as many cambial strips are formed as the number of phloem groups The cambial cells divide tangentially again and again and produce secondary tissues
