Difference b/w syplast and apoplast

Posted by Ananya Sharma 7 years, 9 months ago

CBSE > Class 11 > Biology

1 answers

Anu Verma 7 years, 9 months ago

These are 2 pathways of water movement in roots .water has to cross epidermis ,cortex ,endodermis, pericycleto reach to xylem .In symplast water diffuses in cell cytoplasm and moves forward through plasmodesmata but in apoplast water passes only cell wall and move through intercellular spaces but it's pathway is interrupted by casparian strip on endodermis which is impermeable to water and from there onwards water follows symplast pathway i.e. move into cell cytoplasm . Movement through apoplast is faster than symplast.
