What is the mechanism used for the translocation of sugars in the phloem?
What is the mechanism used for the translocation of sugars in the phloem?
Passive transport
Pressure flow hypothesis
Diffusion
Active transport
Solution
The accepted mechanism used for the translocation of sugars from source to sink is called the pressure flow hypothesis. This mechanism involves the movement of sap in the phloem due to a difference in water potential created by the loading of sugars at the source.
