Endodermis

single layer of cells surrounding the central stele (vascular tissue) in roots. The radial and transverse walls contain the hydrophobic Casparian band, that prevents water flow in or out of the stele through the apoplast. Also present in some stems. A single layer of cells found in many plants, where the endodermis, consisting of endodermal cells regulate the flow of water and other materials into the plant, particularly at the roots.

Apoplast, Symplast

... through the root of a plant. Water in the apoplast pathway moves from cell to cell via spaces in the cellulose cell walls until it reaches the endodermis. At the endodermis, there is the 'apoplast block' - the cellulose cell walls of the cells of the endodermis have a substance called suberin ...

Can plants absorb sucrose?

... Now, on the absorption of solutes: ions are taken up through SPECIFIC transport. Each ion has a special transport protein for its uptake in the endodermis. Cations are usually taken up through uniporters, after being displaced from the binding to soil particles by H+ ions contributed by plant ...
