  2. Cortex (botany) - Wikipedia

    en.wikipedia.org/wiki/Cortex_(botany)

    The loosely packed cells of root cortex allow movement of water and oxygen in the intercellular spaces. [4] One of the main functions of the root cortex is to serve as a storage area for reserve foods. [4] The innermost layer of the cortex in the roots of vascular plants is the endodermis. The endodermis is responsible for storing starch as ...

  3. Endodermis - Wikipedia

    en.wikipedia.org/wiki/Endodermis

    Ranunculus Root Cross Section. The endodermis is the innermost layer of cortex in land plants. It is a cylinder of compact living cells, the radial walls of which are impregnated with hydrophobic substances (Casparian strip) to restrict apoplastic flow of water to the inside. [1] The endodermis is the boundary between the cortex and the stele.

  4. Exodermis - Wikipedia

    en.wikipedia.org/wiki/Exodermis

    The exodermis is a physiological barrier that has a role in root function and protection. [1] The exodermis is a membrane of variable permeability responsible for the radial flow of water, ions, and nutrients. [2] [3] It is the outer layer of a plant's cortex.

  5. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root. Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.

  6. Casparian strip - Wikipedia

    en.wikipedia.org/wiki/Casparian_strip

    At the root, the Casparian strip is embedded within the cell wall of endodermal cells in the non-growing region of the root behind the root tip. [10] Here, the Casparian strip serves as a boundary layer separating the apoplast of the cortex from the apoplast of the vascular tissue thereby blocking diffusion of material between the two. [11]

  7. Stele (biology) - Wikipedia

    en.wikipedia.org/wiki/Stele_(biology)

    Outside the stele lies the endodermis, which is the innermost cell layer of the cortex. The concept of the stele was developed in the late 19th century by French botanists P. E. L. van Tieghem and H. Doultion as a model for understanding the relationship between the shoot and root, and for discussing the evolution of vascular plant morphology. [2]

  9. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    Before the cortex is destroyed, a cork cambium develops there. The cork cambium divides to produce waterproof cork cells externally and sometimes phelloderm cells internally. Those three tissues form the periderm, which replaces the epidermis in function. Areas of loosely packed cells in the periderm that function in gas exchange are called ...
