Correct answer: C. Endodermis
- A. Plasmodcsmala
- B. Cortex
- C. Endodermis
- 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.

About Forms and Functions of Plants
Plant nutrition and transport cover mineral uptake, photosynthesis, xylem movement of water and minerals, and phloem translocation of sugars. Plant growth regulators include auxins, gibberellins, cytokinins, abscisic acid and ethene, whose effects on cell division, elongation, dormancy, fruit ripening and tropic responses should not be confused with mineral nutrition.
