Question

Passage cells are thin - walled cells found in (A) phloem elements that serve as entry points for substance for transport to other plant parts (B) testa of seeds to enable emergence of growing embryonic axis during seed germination (C) central region of style through which the pollen tube grows towards the ovary (D) endodermis of roots facilitating rapid transport of water from cortex to pericycle.

Tardigrade Admin · Accepted Answer

Endodermal cells without Casparian bands are called passage cells. These cells are present opposite to the protoxylem cells. Endodermis acts as a checkpoint, and prevents the outflow of water and minerals from the stele into the cortex, and also acts as a barrier in the inflow of water and minerals from cortex and stele.
So, the correct option is 'endodermis of root facilitates rapid transport of water from cortex to pericycle'
