Answer Key / Explanation : (b) -

(b)

Endodermis is innermost distinct layer of cortex. The endodermis is uniseriate and almost universally present in the roots. The cells of endodermis are living and characterized by presence of Casparian strips or Casparian bands on their anticlinal walls. The strip is formed during the early ontogeny of the cell and is a part of primary wall. The strip is typically located close to the inner tangential wall. Thin-walled passage cells are also found in the endodermal layer, which lie against the protoxylem poles.
