WebThe steps involved in root nodule formation are-. 1) Rhizobium bacteria divides to form colonies which surround the root hairs and epidermal cells of the plant. 2) The root hair gets curled and get invaded by the bacteria. 3) After the invasion, it forms an infection thread that carries the bacteria into the cortex of the root. WebLateral roots, emerging from the pericycle (meristematic tissue), extend horizontally from the primary root (radicle) and over time makeup the iconic branching pattern of root systems. They contribute to anchoring the plant securely into the soil, increasing water uptake, and facilitate the extraction of nutrients required for the growth and development …

WebPericycle of root produces lateral roots. Endodermis is followed by pericycle. Usually it is a continuous layer but in some monocots it is interrupted by xylem and phloem. It is the seat of origin of lateral roots and cork cambium. The root branches are, therefore described as endogenous in origin. The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues it surrounds. In eudicots, it also has the capacity to produce lateral roots.
