Answer:

Source cells are cells that produce sugars and pump them into the phloem, whereas sink cells are cells that do not make enough sugars for their own growth and metabolism and must import them from the phloem. The mechanism of phloem translocation is described in a model of phloem function called the pressure flow model.
