Question

Is a pericycle a ground tissue?

Answer 1

Hint: There are three common types of specialised (differentiated) tissues in vascular plants: dermal tissues, vascular tissues, and ground tissues. Ground tissue is a type of plant tissue that is not found in the dermal or vascular tissues. It is produced by the ground meristem. It fills in the plant's soft portions, such as the cortex, pith, pericycle, and so on. Ground tissue is made up of three different types of cells: parenchyma, sclerenchyma, and collenchyma cells.

Complete answer:
The pericycle is a ground tissue located between endodermis and vascular bundle, it encompasses the outermost area of intrastelar ground tissue. In the cortex, pericycle, pith, and medullary rays, as well as the primary stems and roots, parenchymatous cells are commonly seen.

The pericycle, which lies just inside the endodermis and is the outermost section of the stele of plants, is made up of non-vascular parenchyma cells. Recurrent areas of parenchyma and sclerenchyma make up the pericycle. The pericycle is a unique layer of cells in plants that encircles the vascular tissue in stems and roots and is named from its location. The inner cortical layer, namely the endodermis, surrounds it in roots.

The pericycle has been credited with a variety of functions in both roots and shoots. It is necessary for xylem loading in the root (for example, BOR1, an efflux-type boron transporter for xylem loading, is specifically expressed in the pericycle). It is required for the initiation of lateral roots in angiosperm roots and later becomes involved in secondary growth.

Pericycle cells in a plant's stem essentially operate to safeguard and maintain the plant's structure. They are part of the vascular system and surround the vascular tissue of the xylem and phloem. The xylem is in charge of moving water throughout the plant, whereas the phloem is in charge of delivering nutrients.

Note: The root's pericycle cells are similar, but they do more than only protect and build the root. They also aid in the formation of new roots, which are governed by the pericycle cells. Lateral roots can be branched off to provide the plant additional room to grow and thrive. It has a structure that is similar to the pericycle cells found in stems. A vascular bundle is visible, forming a cylindrical shape. The pericycle cells are all around it.
