Phloem.

Tube vessels inside plant stems that transports sugars and minerals. Do not have strong walls. Translocation* Movement can be in any direction but always moves from where sugar is in abundance (sugar source) to where sugar is needed (sugar sink) Sugar is made in photosynthesizing cells of the plant and can be polymerized and stored as starch in any cells of the plant. The sugar produced in photosynthesis is called glucose. The starch is broken …

…the phloem (sugar source) there is a large amount of solute concentration and a high water content. This exerts a high water (turgor) pressure or hydrostatic pressure. There is a low amount of solute, lower water content and a lower turgor pressure. Water flows along the phloem from the area of high hydrostatic pressure to the area of low hydrostatic pressure that is from source to sink. *The movement of sugars in plants *Adenosine triphosphate
