Question:
The endodermal cells show Casparian strips made up of ______________.
The endodermal cells show Casparian strips made up of ______________.
Show Hint

Updated On: Mar 6, 2026
- cellulose
- cutin
- suberin
- pectin
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding Casparian strips.
Casparian strips are specialized bands present in the radial and transverse walls of endodermal cells in roots.
Step 2: Chemical composition.
These strips are made of suberin, a waxy and hydrophobic substance.
Step 3: Functional significance.
Suberin blocks apoplastic movement of water, forcing selective absorption through cell membranes.
Step 4: Conclusion.
Hence, Casparian strips are made up of suberin.
