plant transport - Coggle Diagram

- - - - increases water vapour concentration gradient (between intermolecular and atmospher)
        
        water diffuses out of leaf at higher rate
- - - - definition: suction force caused by transpiration which results in water to move up the xylem
        
        transpirational stream
    - - light
        
        stomata open wider in light
      - temp
        
        more evap and diffusion, more water lsot
      - wind
        
        more water out of leaves due to steeper concentration gradient as water is removed quickly
      - humidity
        
        diffusion of water slow down if the leaf is already surrounded by moist air
    - - loss of water from mesophyll cells cause water potential of cells to decrease
        
        thiscauses cells to draw water from cells deeper inside the leaf which in turn draw water from the xylem
        
        generating suction force (transpirational pull) that pulls continuous column of water from (source)
- - - - reduces water loss
  - - - lose turgor pressure
- - - - however, photodynthesis and cell turgor liquid is ASSUMED TO BE mostly negligible
      - NOT the same as rate of water loss as water drawn up may also be used to other purposes (photosynthesis/maintaining cell turgor)
