Upgraded B002 Ntbi0503 Radial Formation Directionality Secondary — a labelled NEET Biology diagram with a definitions lexicon.
Diagram illustrating the radial formation and directionality of secondary xylem and phloem. Labelled parts: Secondary Xylem, Cross-section, Dicot Stem, Cambium, Growth, Phloem, outward. Wood formed inside the vascular cambium during secondary growth. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. A plant stem characterized by the arrangement of vascular bundles in a ring and the presence of a distinct pith and cortex. FYI: Dicot stems typically exhibit secondary growth due to the presence of fascicular and interfascicular cambium. A lateral meristem responsible for secondary growth in plants. It is typically composed of vascular cambium (producing xylem and phloem) and cork cambium (producing cork). FYI: The vascular cambium is responsible for the formation of secondary xylem and secondary phloem, leading to the increase in girth (secondary growth). Increase in size or mass; can occur in non-living matter like crystals. Vascular tissue responsible for the transport of sugars and metabolic products downward from the leaves. outward is a labeled feature or concept in this upgraded BioAtlas image: A highly labeled cross-section focusing on the vascular cambium zone, with clear arrows indicating inward (secondary xylem) and outward (secondary phloem) growth.
