Growth Secondary Html 35 10secondgrowth Jpg Secondary growth occurs in the lateral meristems comprising two types of cells. the vascular cambium adds layers of vascular tissue called secondary xylem (wood) and secondary phloem . the cork cambium replaces the epidermis with periderm, which is thicker and tougher. Apical meristem initiates primary growth, producing primary xylem and primary phloem, as well as the vascular cambium. secondary growth occurs at the vascular cambium , which forms secondary xylem (wood) and secondary phloem (inner bark).
Growth Secondary Html 35 10secondgrowth Jpg Study with quizlet and memorize flashcards containing terms like primary growth, which occurs at apical meristems, results in the elongation of roots and shoots. in roots, primary growth increases water and nutrient absorption by increasing the root surface area exposed to the soil. in shoots, primary growth adds height and leaves, which increase the plant's exposure to and absorption of light. Figure 30.4.1 30.4. 1: primary and secondary growth: in woody plants, primary growth is followed by secondary growth, which allows the plant stem to increase in thickness or girth. secondary vascular tissue is added as the plant grows, as well as a cork layer. the bark of a tree extends from the vascular cambium to the epidermis. They grow through a combination of cell growth and cell division (mitosis). the key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth). Photo by maria morrow, cc by 4.0. figure 12.2.2 12.2. 2: a cross section of a pine stem that is 4 years old. the epidermis is gone and several layers of periderm (outer bark) have formed around the outside of the stem. tears in the periderm form lenticels. inside the periderm is cortex with embedded resin canals.

Iii. secondary growth in roots i. some important definitions: primary tissues: tissues generated from the growth of an apical meristem. cambium: a lateral meristem constituting a sheet of cells. growth of these cells increases the girdth of the plant organ involved. secondary tissues: tissues generated from the growth of a cambium. Secondary growth. growth in plants occurs in two ways: primary and secondary. 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.
