 The cambium is a specialized region of cells located between the xylem and phloem layers of a plant's vascular system. It is responsible for the radial growth of the plant, which is essential for the formation of new leaves, flowers, and fruits. This process has been difficult to study experimentally because it occurs inside living cells, but researchers have developed a computer simulation model that can accurately replicate the structure and function of the cambium. The model uses data from experiments to determine how the cambium works, and it also takes into account the physical constraints of the plant's tissues. The model suggests that only a few key components are necessary for the proper functioning of the cambium, and that these components work together to produce radial growth.
