Correct answer: C. Endodennis
- A. Plasmodcsmala
- B. Cortex
- C. Endodennis
- D. Pith
Explanation
In roots, the apoplast pathway of water is disrupted when water reaches the endodermis. The endodermis is a specialized layer of cells in the root that is characterized by the presence of the Casparian strip, a waxy barrier made of suberin. The Casparian strip blocks the apoplastic movement of water and minerals, forcing substances to enter the symplast pathway by crossing the cell membranes of the endodermal cells.
