At the time of unloading of phloem, which of the following does not happen?
High water potential in phloem
Returning of water to sink
Active transport of sucrose to sink
All of these
Meanwhile, at the sink, incoming sugars are actively transported out of the phloem and removed as complex carbohydrates.
The loss of solute produces a high water potential in the phloem, and water passes out, returning eventually to xylem.
