endodermis
Quick Summary
The endodermis is the innermost layer of the cortex in plant roots and some herbaceous stems. It is composed of tightly packed cells that regulate the flow of water and minerals between the outer cortex and the central vascular cylinder. A key feature of endodermal cells is the presence of a Casparian strip within their cell walls, which is a waterproof band that controls the movement of substances into the vascular cylinder. This layer is crucial for managing water and nutrient uptake by the roots.123

plant developmentThe root tipAn internal protective band, the endodermis, becomes conspicuous as a single sheath of cells surrounding the procambium. The phloem procambium, recognizable by its narrow cells, begins to differentiate in the lower part of the region of elongation. The xylem also becomes distinct, the thickenings appearing first in the upper part…
