The diagram shows a section of the phloem pathway, including neighbouring cells, extending from leaf to root. Which process is taking place between 1 to 2 and what effect does it have on the water potential at 2?
- Aactive transport of sucrose - becomes less negative
- Bactive transport of sucrose - becomes more negative
- Cdiffusion of sucrose - becomes less negative
- Ddiffusion of sucrose - becomes more negative
