Question

How do apoplastic and symplastic movement occurs in plants?

Answer 1

apoplastic movement means movement is through cell walls of cell
symplastic movement occurs through cytoplasm freely..

hope it helps...

Answer 2

Apoplastic pathway :-
Here water passes from root hair to xylem through the walls of intervening cells without crossing any membrane or cytoplasm. This pathway provides the least resistance to movement of water. However, it is interrupted by the presence of impermeable lignosuberin casparian strips in the walls of endodermal cells.

Symplastic pathway:-
Here individual root cells function as tiny osmotic systems. The first osmotic system operates at root hair cell. It absorbs water from soil through osmosis. The pathway is cell wall, plasma-lemma, cytoplasm, tonoplast and central vacuole. From root hair eel, water passes into vacuoles of adjacent cortical cell through osmosis.

The process continues till water reaches the xylem parenchyma cells. However, vacuolar pathway provides a lot of resistance. It is used only when individual cells are to pick up water. Otherwise, the usual pathway of water movement is partly apoplastic and partly symplastic.
