Transport Processes
Long distance transport Phloem 
-
-
-
in some species, phloem is loaded with polymer trap mechanism
-
specific mass transfer
to make comparison easy, mass cell can be divide by cross sectional area of phloem

-
Cell and Water Movement
water moves from regions where it is relatively concentrated to regions where it is less concentrated
A cell's water potential can be made more negative depolymerizing polymers to monomers pumping solutes such as potassium ions & sucrose
at the incipient plasmolysis, the chloroplasts has lost just enough water that is no longer present against the wall & water pressure equals zero
Water Potential
-
matric potential
water adhesion to non solved structures such as cell walls, membranes & soil

long distance transport Xylem
-

-
Short distance intercellular transport
apoplast- most small molecules can move easily through bot the wall and the intercellular space; two together

Diffusion
-
Osmosis
