Question

Casparian strip is

• A. Lens-like thickenings of endodermal cells
• B. Strip of thickening found on the outer side of endodermis
• C. Ligno-suberin band running in endodermal cell walls
• D. Layer of cells between endodermis and cortex

Answer 1

Answer: (C)

Ligno-suberin band running in endodermal cell walls

In the endodermal cells, lingo-suberised thickenings are present on the radial and tangential cell walls. These are called Casparian strip.

So the correct option is ‘Ligno-suberised band running in endodermal cell walls.
