Question

According to pressure flow hypothesis of phloem transport

Answer 1

food flows upward direction and downward direction. by ossmotic pressure.

Answer 2

Answer:

The Pressure Flow Hypothesis, also known as the Mass Flow Hypothesis, is the best-supported theory to explain the movement of sap through the phloem.

Explanation:

The pressure flow hypothesis of food movement states that dissolved sugars flow from sources and are released at sinks where they are used. This movement of sugars creates a pressure difference between the source and the sink, allowing for continued movement of dissolved sugars in the phloem
