The plant carries the water sucked up from the root to the whole through fibrovascular bundle. It is known that these two[Apoplast],[Symplast] routes exist and It is thought that Aquaporin promotes the transportation of water by Symplast.

Therefore, it is thought that the transportation of water and the transportation of the ion are independent respectively.
