Question

Apoplastic movement of water occurs exclusively through the cell wall and intercellular spaces without losing any membrane it is continuous throughout the plant accepted the band of surprised matrix called casparian strips

Answer 1

Answer:

Hey mate here is your answer.....

In plant anatomy, the Casparian strip is a band of cell wall material deposited in the radial and transverse walls of the endodermis, and is chemically different from the rest of the cell wall - the cell wall being made of lignin

[1]

and without suberin - whereas the Casparian strip is made of suberin and sometimes lignin..

hope it's helpful for you...

Answer 2

$\huge\red{\boxed{\bold{Answer}}}$

✔ Statement : Apoplastic movement of Water occurs exclusively through the cell wall and intercellular spaces .it is continuous except at casparian strips..

❇EXPLANATION::

✳Plants absorb most of the water through the roots from the soil.

✳Once water is absorbed by root hairs it can follow two distinct pathways.

1.APOPLASTIC PATHWAY.

2.SYMPLASTIC PATHWAY.

❇APOPLASTIC PATHWAY::

➡In this pathway water passes from root hairs to xylem Through inter cellular spaces and walls .

➡Without crossing any membrane or cytoplasm.

➡This pathway provides least resistance to the movement of water .

➡This pathway is interuppted by the presence of casparian strips as it is suberin deposited layer .so Then symplast occurs .

❇SYMPLASTIC PATHWAY::

➡This pathway is formed by the system of interconnected protoplasts of different cells .

➡ Hence movement is relatively slow

➡This pathway involves crossing of membranes.

➡So we can say that up to the before of endodermis symplast occurs after it follows symplast for crossing membranes .
