Dicot Leaf Cross Section Showing Mesophyll Layers — a labelled NEET Biology diagram with a definitions lexicon.
Dicot leaf cross-section showing mesophyll layers. Labelled parts: Palisade Mesophyll, Spongy Mesophyll, Cross-section, Mesophyll, Epidermis, dicot leaf, dorsiventral, Polyarch vascular bundles. A layer of vertically elongated cells rich in chloroplasts found just beneath the upper epidermis of leaves. The lower layer of leaf mesophyll consisting of loosely arranged, irregularly shaped cells with large air spaces. FYI: These air spaces facilitate rapid gaseous exchange between the atmosphere and the photosynthetic cells. 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. The ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis. The outermost protective layer of cells in plants, often covered by a waxy cuticle to prevent water loss. FYI: In roots, the epidermis contains specialized extensions called root hairs for water absorption. dicot leaf is a key labeled feature or concept in this BioAtlas visual: A labeled diagram of a dicot leaf cross-section (dorsiventral), clearly distinguishing the upper epidermis, palisade mesophyll layer, spongy mesophyll layer, and vascu... dorsiventral is a key labeled feature or concept in this BioAtlas visual: A labeled diagram of a dicot leaf cross-section (dorsiventral), clearly distinguishing the upper epidermis, palisade mesophyll layer, spongy mesophyll layer, and vascu... A type of vascular arrangement where multiple vascular bundles are present in the stem or root. This arrangement is characteristic of dicot stems. FYI: In dicot stems, the vascular bundles are typically arranged in a ring pattern, making them polyarch.
