A key label in the BioAtlas entry 'Dicot Root Cross-Section (T.S.)'. Review and refine this definition before adding it to the live lexicon. A key label in the BioAtlas entry 'Dicot Root Cross-Section (T.S.)'. Review and refine this definition before adding it to the live lexicon. 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. A key label in the BioAtlas entry 'Dicot Root Cross-Section (T.S.)'. Review and refine this definition before adding it to the live lexicon. The tissue layer in plant stems and roots located between the epidermis and the vascular cylinder, primarily used for storage. FYI: In many plants, the innermost layer of the cortex is the endodermis, which contains the Casparian strip. A type of simple permanent tissue composed of loosely packed, thin-walled cells with large intercellular spaces. These cells are primarily involved in storage and basic metabolic functions. FYI: Parenchyma tissue is metabolically active and is often found in the pith of stems and the cortex of roots, serving as a storage site for starch and water. The innermost layer of the cortex surrounding the vascular cylinder (stele). It regulates the movement of water and solutes into the vascular tissues. FYI: The endodermis contains the Casparian strips, waxy bands that force water to pass through the cell cytoplasm, making the plant apoplastic pathway difficult. A band of cell wall material deposited in the radial and transverse walls of the endodermis, chemically different from the rest of the cell wall. A layer of meristematic cells located immediately internal to the endodermis. It is responsible for initiating the growth of lateral roots. FYI: The pericycle is the site from which most lateral roots originate, making it vital for root system development. A root vascular pattern with four xylem arms radiating from the center. A key label in the BioAtlas entry 'Dicot Root Cross-Section (T.S.)'. Review and refine this definition before adding it to the live lexicon. Vascular tissue responsible for the transport of sugars and metabolic products downward from the leaves. The soft, spongy central cylinder of parenchymatous tissue in the stems of dicotyledonous plants.
