Problem
1. Why sucrose is used for phloem transport instead of glucose
2. Describe active transport of sucrose into phloem via co-transport protein
3. Explain phloem loading
4. State phloem becomes hypertonic to xylem due to active transport of sucrose into phloem
5. State water moves into phloem by osmosis
6. Outline why pressure in phloem increases due to the movement of water into phloem
7. Explain phloem unloading in sink tissue
8. Water rejoins transpiration stream
9. State that water moves from high to low pressure and movement of water moves solutes dissolved in it
10. Removal of water decreases pressure
11. Sucrose moved into sink cells, converted to starch or back to glucose.
