Explain the pressure-flow hypothesis by first completing the statements with the terms provided, and then rearranging the statements so that they appear in chronological order.

The diagram shows a model which can be used to demonstrate mass flow of materials through phloem tissue from the region of synthesis [source] to the storage organs [sink]. X and Y are filled with sucrose solutions of different concentration, causing water to move in or out of X and Y by osmosis or as a result of hydrostatic pressure. Sucrose solution then moves through tube T joining X and Y What will be the direction of movement of sucrose solution in tube T? Why?

Which molecular forces are more important for phloem transport? Select all that apply Cohesion of water molecules to one another Adhesion of water molecules to other surfaces Turgor pressure Changes in tonicity Question 6 During phloem transport, which of the following occur at, or close to the sink? Select all that apply Sugars move out of sieve tubes by active transport Sugars move into sieve tubes by active transport Water moves from the xylem into the sieve tubes Water moves from phloem into the xylem Solution in sieve tubes becomes hypertonic Solution in sieve tubes becomes hypotonic
