Upgraded B002 Ntbi1002 Driving Forces Xylem Phloem — a labelled NEET Biology diagram with a definitions lexicon.
Conceptual diagram comparing the driving forces of xylem and phloem. Labelled parts: Cross-section, Phloem, Secondary Xylem, Evidence. 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. Vascular tissue responsible for the transport of sugars and metabolic products downward from the leaves. Wood formed inside the vascular cambium during secondary growth. Evidence is a labeled feature or concept in this upgraded BioAtlas image: A labeled schematic showing a cross-section. One side (Xylem) shows water flowing up with an arrow labeled 'Tension/Transpiration Pull'. The other side (Phloem) shows sap flowin...
