According to the Pressure Flow Hypothesis of Phloem Transport

question 60

Multiple Choice

According to the pressure flow hypothesis of phloem transport,

• A) solute moves from a high concentration in the source to a lower concentration in the sink.
• B) water is actively transported into the source region of the phloem to create the turgor pressure needed.
• C) the combination of a high turgor pressure in the source and transpiration water loss from the sink moves solutes through phloem conduits.
• D) the formation of starch from sugar in the sink increases the osmotic concentration.
• E) the pressure in the phloem of a root is normally greater than the pressure in the phloem of a leaf.
