Here's why:

* Endodermis: This is a layer of cells found in the roots and stems of vascular plants. It plays a crucial role in regulating the movement of water and nutrients into the vascular tissue (xylem and phloem).

* Skin: This is the outermost layer of an organism's body, providing protection and acting as a barrier. In animals, it's composed of epithelial tissue.

While both endodermis and skin are layers of cells, they have different functions and locations within the organism.
