It is a mass of parenchyma cells lying in between the xylem and phloem bundles. 6. Pith. It occupies the central portion of the root and consists of parenchymatous cells. Unlike dicot roots, it is well-developed in monocot roots. 7. Vascular Bundles. The vascular tissue in monocot roots is polyarch.

WebbIn Arabidopsis, lateral roots originate from pericycle cells deep within the primary root. New lateral root primordia (LRP) have to emerge through several overlaying tissues. Here, we report that auxin produced in new LRP is transported towards the outer tissues where it triggers cell separation by inducing both the auxin influx carrier LAX3 and cell-wall … WebbThe layer of plant tissue, 1 to several cells thick, that lies between the endodermis and the phloem.

WebbFunction: The pericycle supports the root, protects its vascular structures, stores nutrients, and facilitates root growth. Pericycle cells can divide and give rise to lateral roots in both monocots and dicots. In dicots, the pericycle also generates meristem cells that support secondary root growth and the cambium that produces xylem and phloem.

WebbThe following points highlight the top four types of ground tissues in plants. The types are: 1. Cortex 2. Endodermis 3. Pericycle 4. Pith. Ground Tissues: Type # 1. Cortex: The ground tissue found beneath the epidermis which surrounds the central cylinder and is delimited from the cylinder by the endodermis is called the cortex.
