Summary Introduction

To analyze:

The claim made by a person that phloem always carries sugars down a plant.

Introduction:

Along a pressure gradient, the sugars are transported from the source to the sink. The source is a part from which the sugars enter into the phloem and the sink is a part where the sugars are deposited by the phloem. This translocation of sugars was described by the Munch pressure-flow model.
