Every winter, the cohesion of water molecules in xylem is interrupted by ice formation. What do trees do in the spring that compensates for this problem?*

Transport of materials in the phloem tissue is mostly downward in the plant whereas bulk flow in xylem is mostly: -upward. -also downward. -very little transport occurs in xylem. -sideways. -the flow of sugars.

Explain the pressure flow theory of phloem transport.
