Summary Introduction
Introduction: Sugars are made by plants during photosynthesis, which are carried throughout the plant by the vascular system. Phloem is responsible for carrying out dissolved sugars from leaves to storage sites of the plants. Sugar moves from the area of high osmotic concentration and high water pressure known as sources to the region of low osmotic concentration and low pressure of water known as sinks.
