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.

Answer 1

Passage cells are thin-walled cells found in

option:(d) Endodermis of roots of facilitate rapid transport of water from cortex to pericycle.

Because of the following reason

*Endodermal cells without Casparian bands are called passage cells.

* These cells are present opposite to the protoxylem.

*Endodermis acts as a checkpoint, and prevents the outflow.

Answer 2

Endodermis of roots facilitating rapid

transport of water from cortex to pericycle.

Explanation:

• The transport of water from the soil to the xylem is a complex process.

• Firstly the water is absorbed from the soil through the root hair cells.

• These root hair cells are the cells of epidermis with less thick cell wall.

• These cells then pass the water to the cortical cells.

• The water through cortical cells move via two processes - through the cells and through the intercellular spaces.

• The water then reaches the endodermis.

• Endodermis is a lignin walled cells which are water tight.

• There are passage cells in between the endodermis which are parenchymatous cells that lead the water enter inside the endodermis into the xylem.
