The rhizoplane refers to the region of soil directly in contact with the root surface, where many interactions between the root and soil microorganisms occur. The other options are not specific to this region of soil. The stele is the central cylinder of tissue within the root, the cortex is the outer layer of tissue between the stele and epidermis, the root cap is a protective layer of cells at the tip of the root, and the rhizosphere is the soil environment influenced by the root through exudation of compounds such as sugars and enzymes.
