Tube vessels inside plant stems that transports sugars and minerals. Do not have strong walls.

…showed last 75 words of 279 total…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.
