Definitions of ENDODERMIS
- The deepest layer of the skin.
- (botany) In a plant stem or root, a cylinder of cells that separates the outer cortex from the central core. The endodermis controls flow of water and minerals within the plant. In most plants, this tissue is restricted to the roots.

Examples of Using ENDODERMIS in a Sentence
- The cells of the endodermis typically have their primary cell walls thickened on four sides radial and transverse with suberin, a water-impermeable waxy substance which in young endodermal cells is deposited in distinctive bands called Casparian strips.
- The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants.
- Once the SCNs have gained entry into the root, they can create specialized feeding cells called syncytia by penetrating the pericycle, endodermis, or cortex cell with their stylet in order to take in nutrients from the plant.
- Emil Godlewski (senior) (1884) proposed Relay pump or Clamberinh force theory (through xylem parenchyma) and Jagadish Chandra Bose(1923) proposed pulsation theory (due to pulsatory activities of innermost cortical cells just outside endodermis).
- A cortex consisting of hypodermis (collenchyma cells) and endodermis (starch containing cells) is present above the pericycle and vascular bundles.
- Nodule lobe primordia develop in the pericycle, endodermis or cortex during the development of the prenodule and finally the bacterium enters the cells of these to infect the new nodule.
- Similar to the endodermis, the exodermis contains very compact cells and is surrounded by a Casparian band, two features which are used to restrict the flow of water to a symplastic fashion (through the cytoplasm) rather than apoplastic fashion which (through the cell wall) flow through passages through the cells' membranes called plasmodesmata.
- The spatial expression of MCA1 and MCA2 and the changes in calcium concentration in the pericycle and endodermis suggests that both MCA1 and MCA2 play a role in symplastic calcium transport and signaling.
