WebIn seed plants, lateral root initiation (LRI) typically takes place close to the meristematic region in the root tip in an internal cell layer called the pericycle. Current hypotheses as to how pericycle cells become committed to forming lateral roots are discussed, along with the cellular basis and genetic control of LRI. WebIn seed plants, lateral root initiation (LRI) typically takes place close to the meristematic region in the root tip in an internal cell layer called the pericycle. Current hypotheses as to …

WebA typical root has four regions in its longitudinal section. Root cap is parenchymatous, a cap-like multicellular structure that covers the root apical meristem. It secretes mucilage to lubricate the path of root in soil. Root cap is followed by 1 mm long zone of growth, i.e., meristematic zone. The meristematic zone is characterized by ... Web1. Anatomically, the root consists of epidermis, cortex and stele. 2. The epidermis gives rise to many root hairs. 3. The cortex is several cells in thickness, and outer few layers often become heavily sclerified. 4. The stele is monarch, diarch or triarch with one, two or three protoxylem groups. 5. cheap mini freezers for sale
