Passage cells are thin walled cells found in

Options

A. endodermis of roots facilitating rapid transport of water from cortex to pericycle
B. phloem elements that serve as entry points for substances for transport to other plant parts
C. testa of seeds to enable emergence of growing embryonic axis during seeds germination
D. central region of style through which the pollen tube grows towards the ovary

Answer

A

Explanation

In roots, endodermis is the innermost layer of cortex. Some of the endodermal cells present opposite to the xylem patched are thin-walled and are called passage cells or transfusion cells. Passage cells help in the transfer of water and dissolved salts from the cortex directly into the xylem and ultimately to the pericycle.
