1.xylem 2.parenchyma 3.vascular cambium 4.phloem Question 2 How does sugar move through a plant? 1.Guard cells build up pressure, allowing dissolved sugars to enter the stomata. 2.Phloem in a sink region has lower pressure than in a source, so sugars flow out at the sink as water diffuses. 3.When the concentration of solute in the sieve tubes gets too low, osmosis allows water to flow in. 4.The pressure gradient allows dissolved sugars to reach high levels in the xylem, pushing them to a sink where they are released.
