Question

Casparian strips are present in the ___________of root and have depositions of______

• A. endodermis, chitin
• B. endodermis, suberin
• C. pericycle, suberin
• D. epiblema, suberin

Answer 1

The correct option is B endodermis, suberin

The radial and tangential walls of endodermis have a deposition of suberin . These are called casparian strips. Suberin is impervious to water.

The epidermis layer of roots is called epiblema.
Pericycle is present inner to endodermis. Initiation of lateral roots takes place in the cells of the pericycle. Plants lack chitin. Chitin is a polysaccharide and is found in the cell wall of fungi and exoskeleton of arthropods.
