Biology EndodermEndomembrane system

Endodermis is the bottom layer of skin.
In plants, it is a thin layer of parenchyma found in roots, just outside the vascular cylinder. It regulates the flow of water.

 


endodermis -- Literally "inner skin", this is a layer of cells which surrounds the central core of vascular tissue, and which helps to regulate the flow of water and dissolved substances.

endodermis Innermost layer of the root cortex surrounding the stele; many of the endodermal cells have Casparian strips.
endodyogeny Same as endopolyogeny except that only two daughter cells are formed.

The endodermis has a strip of water-proof material (containing suberin) known as the Casparian strip that forces water through the endodermal cell and in such a way regulates the amount of water getting to the xylem.

In the absence of secondary growth (most monocotyledons and a few dicotyledons) the endodermis commonly undergoes certain wall modifications.
