Overtime work, Vascular plant development of secondary growth One of them has evolved to adapt to new and changing environment. Growth is defined as increasing secondary stem, root or branched diameter. To the increasing number of needs of dicotyledonous plants and gymnosperm plant transplanted tissues to sunlight, such growth can develop and evolve. The cork layer is formed on both sides of the mitotic organization of stem, stem, cork and cork.
Secondary meristematic tissue allows growth of wood diameter (secondary growth). Secondary growth without herbs. Two types of secondary meristematic tissue forming the layer are "exchange" or meaning, named, "change". Angiogenesis increases the diameter to the plant, (toward the outside of the stem or roots ) Secondary xylem (toward the center of the stem or root) layer and phloem. In this process, we will create a tree and build a solid trunk. Cork layer is one of coniferous trees formed instead between the skin and phloem part of the epidermal trunk bark and roots
Woody plants grow in two ways. Major growth length or height increases, mediate shoot and tip of apical meristematic tissue - it is difficult to clarify in the cross section of the figure. The (inner) vascularization layer increases the diameter of the stem or root by adding wood and forming the sieve (outward), cork bark-substituted epidermal layer, and hypertrophied growth
Main growth of stem and root elongation. Conversion of the outer layer is formed as a bark of phloem cells including new tree and secondary growth, including thickening and strengthening tissues. I do not bark any flexibility. Eventually growth slows down and stops trees, it is no longer high. In the event of damage, the trees may be empty in time. Leaves are structures designed for photosynthesis and are arranged in a tree to maximize exposure to light without shielding each other in such a way. They can be tricky, which is an important investment on trees, or plants including stones, lignin, tannins and poisons to prevent herbivores. Tree leaves have evolved in various shapes and sizes in response to environmental stresses, such as climate and predation. They may be evergreen or fallen leaves wide or needlelike, simple or complex, lobes or whole, smooth or hairy, delicate or tough
