Question

what is apoplast pathways ​

Answer 1

Answer:

(1) The movement of water across the root cells occur by two pathways viz. apoplast and symplast.

(2) Apoplast movement of water in plants occurs exclusively through cell walls and intercelular spaces in living cells of cortex.

3) Apoplast pathway is up to the endodermis as the suberized layer of Casparian strip obstructs the movement.

(4) Additional apoplastic route iving direct contact to xylem and phloem is through secondary roots which originate at pericycle and bypass endodermis.

(5) The cellulosic walls of root hair, cortical cells are hydrophilic and permeable to water.
