AbstractWhen a plant root is reoriented within the gravity field, it responds by initiating a curvature which eventually results in vertical growth. Gravity sensing occurs primarily in the root tip. It may involve amyloplast sedimentation in the columella cells of the root cap, or the detection of forces exerted by the mass of the protoplast on ...

Several types of resorption affect teeth: internal, external, invasive, pressure, and idiopathic resorption. Diagnosis depends on an accurate medical and dental history, and radiographic and clinical examination. Because trauma appears to be a major factor associated with resorption, questions regarding past traumatic events may provide good leads to a

Root system defined as the Hidden Half of plant, has not attracted a great deal of attention for a long time from plant biologists. In recent years, through the new innovative techniques, root system has been deeply studied allowing all to reveal its structure, function, but also its genetic potential, which could be manipulated to improve crop yield ...

A t one time, scientists thought that mountains and valleys arise because the earth is shrinking; all the wrinkles, folds, faults and other deformations in the planet's crust were likened to the crinkly skin of a drying apple. Then came the theory of plate tectonics, which revolutionized the earth sciences and gave researchers a more tenable framework ...
