What occurs at the sink to reduce osmotic pressure in the phloem?
What occurs at the sink to reduce osmotic pressure in the phloem?
Loading of the phloem
Active transport of the sucrose out of the phloem
Passive transport of the sucrose out of the phloem
Diffusion of the sucrose out of the phloem
Solution
At the sink, incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. This active transport reduces the osmotic pressure in the phloem, allowing water to move out and return to the xylem.
