Growth In Monocot Stems
Growth inside a monocot cell is different from the growth in a dicot cell. This is mainly due to the arrangement of the xylem and phloem. In monocot cells the xylem and phloem are arranged in vascular bundles, scattered throughout the stem. These are the type of cells which make up all annuals and most biennials because they have no need to increase the size of their stems. A monocot cell system is unable to produce new layers of a xylem and phloem because they lacks a vascular cambium. A monocot stem does not increase much in width only in height.
