Question

Quizplus · Accepted Answer

The pressure flow mechanism, also known as the mass flow hypothesis, is the most widely accepted model explaining phloem sap movement in plants. It suggests that sugars are actively transported into phloem sieve tubes, creating a high osmotic pressure that draws water into the tubes, generating a pressure that drives the sap to areas of lower pressure/sugar concentration.
