Following are the differences between apoplast pathway and symplast pathway. Apoplast pathway Symplast pathway (i) It consists of non- living parts of plant body, i.e., cell walls and intercellular spaces. It consists of living parts of plant body, i.e., protoplasts connected by plasmodesmata. (ii) There is little resistance in the movement of water. Some resistance occurs in the movement of water through symplast. (iii) It is slightly slower. It is faster. (iv) Metabolic state of root directly affects apoplast pathway. Metabolic state of root does not affect symplast pathway. Which of the given differences is/are incorrect ?

Apoplast pathway is faster while symplast pathway is slightly slower. Metabolic state of root does not affect apoplast pathway while metabolic state of root directly affects symplast pathway.

	Apoplast pathway	Symplast pathway
(i)	It consists of non- living parts of plant body, i.e., cell walls and intercellular spaces.	It consists of living parts of plant body, i.e., protoplasts connected by plasmodesmata.
(ii)	There is little resistance in the movement of water.	Some resistance occurs in the movement of water through symplast.
(iii)	It is slightly slower.	It is faster.
(iv)	Metabolic state of root directly affects apoplast pathway.	Metabolic state of root does not affect symplast pathway.
