What is osmotic potential in plants?

Open 1 Answers Plant Water Relations

1 Answer


The movement of water molecules occurs due to the difference in the osmotic potential. The water molecules move from the region of high osmotic potential to a region of low osmotic potential. The uptake of the water molecules occurring through the root is mainly because of the osmotic potential. This difference in the osmotic potential drives the water from the root to the upper parts of the tree.
