Which process is most important for long-distance transportation within the plant?

What represents the water potential of a plant?

What does the letter “c” in the root tip diagram below refer to?

What kind of process is this for the plant, in terms of energy use?

The “polymer-trapping model” explains how _?_ loading occurs in the phloem. 

Name the cells in this type of tissue that are dead cells with thick secondary cell walls to provide strength for non-growing parts of the plant. _______

List ONE (1) the three osmotically active ions that are most important in the process described above. _______

Water moves through soil primarily by what transport process?

a) Describe and explain in detail, step by step, the pressure-flow hypothesis of translocation in the phloem.  Each step should be explained in a separate paragraph.  For each step, be sure to describe/explain relevant information about processes, water potential status, what does and does not require energy and why, etc.  b) What factors determine to which “sink” the phloem solution will flow?

The membrane surrounding that large water-filled storage space is called what?
