 Assertion is correct because the absence of a distinct cuticle and stomata distinguishes the epidermis of the root from that of the stem.

Reason is incorrect because There are some endodermal cells close to the protoxylem that lack Casparian strips and are referred to as transfusion cells or passage cells. Water and minerals can diffuse radially through the endodermis because of these cells.

Option 3 is correct.
