Question

Choose the correct answers from the alternatives given.
The Casparian strip is found

• A. within the secondary wall of parenchyma cells
• B. on four sides of endodermal cells
• C. between xylem and phloem cells
• D. between all epidermal cells

Answer 1

The correct option is B on four sides of endodermal cells

The Casparian strip is a band of cell wall material deposited in the radial and transverse walls of the endodermis and is chemically different from the rest of the cell wall - the cell wall is made of lignin and without suberin - whereas the Casparian strip is made of suberin and sometimes lignin.

Hence, the correct answer is 'on four sides of endodermal cells'.
