The protoosmotic model for phloem transport is a concept in plant physiology that explains the movement of assimilates, primarily sugars like sucrose, through the phloem. This model is based on the principle that osmotic pressure differences between source and sink tissues drive the flow of phloem sap. According to the model, sugars are actively loaded into the sieve tubes at the source, typically mature leaves, increasing the osmotic potential inside the phloem. This
