Transport process (long distance transport phloem and xylem (cohesion…

- - - - by polymer trap mechanism
      - sinks are sites
        
        receive transported phloem sap
  - - - xylem vessels & tracheas
  - - - force acting on molecule acts on another
    - - molecules interesting with other substance
  - - - increased transportation
    - - decreased transportation
    - - pores in leaf
        
        allow gas exchange
  - - - through plant & evaporation
  - - - specific mass transfer
    - - tune into sieve elements
- - - - increased surface ares
  - - - adjust H2O potential turgidity
    - - alters turgidity
        
        cell shape
  - - - K ions transported
        
        loss of K ions
        
        negative potential
        
        absorption of K ions
        
        increasingly negative
    - - hydraulic equilibrium
      - H2O enters & leaves
        
        no net change
- - - - protein
        
        binds to molecule & ATP
        
        ATP to ADP
        
        energy to pump
      - ATP for molecule movement
        
        across gradient
    - - vesicle moves in cytoplasm
        
        fusses with organelle
  - - - nothing gets through
      - isolation barriers
    - - molecules move through
      - no biological significance
    - - hydrophobic pass through
      - hydrophilic cross differentially
        
        protein channel
        
        aquaporins
      - certain substances move through
      - lips & proteins
- - - - solute
      - solvent
      - effect on H2O
    - - effects water potential
      - water under tension
      - postive or negative
      - pressure potential increases
      - water potential decreases
      - H2O under pressure
