Compare transpiration and translocation, and be sure to cover the five points below.
1. Principal substance(s) transported
2. Direction of transport
3. Tissue through which transport occurs
4. Name of model that explains the process
5. Does the plant expend energy to carry out the process?
Transpiration
The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released into the atmosphere.
Translocation
The process in plants where nutrients and sugars produced in the leaves are transported to other parts of the plant through the phloem.
- Familiarize yourself with the operations, directionality, and energy prerequisites for transpiration and translocation phenomena in plants.

Final Answer :
1. Transpiration: water and minerals; translocation: dissolved sugars
2. Transpiration: upward; translocation: both upward and downward
3. Transpiration: xylem; translocation: phloem
4. Transpiration: tension-cohesion (or transpiration-cohesion) model; translocation: pressure-flow model
5. Transpiration: no; translocation: only to load/unload sugars
