The pericycle is located between the endodermis and phloem in plant roots. It moves these solutes from epidermis cells through the cortex into the endodermis. The Casparian strip in the endodermis roots and cork cells of plant bark contain suberin. Once inside the endodermis, the ions are in the symplast pathway. The endodermis in the root is important in the development of root pressure. Outside the stele lies the endodermis, which is the innermost cell layer of the cortex. The innermost layer of the cortex is the endodermis. The endodermis is developmentally the innermost portion of the cortex. Instead, water must bypass the endodermis via the symplast. The endodermis is the boundary between the cortex and the stele. The Endodermis is the central, innermost layer of cortex in land plants. Pink-colored "jeolpyeon", called "songgi-jeolpyeon" (), is made by pounding "tteok" with pine endodermis. The endodermis is a single layer of cells between the cortex and the pericycle.
