C.3.4 - transportation in plant

• Photosynthesis - light -> sugar

  • 6H2O + 6CO2 -> C6H12O6 + 6O2
  • Chlorophyll traps light
• Photosynthesis

  • SOURCE: leaves
  • SINK: roots, sugar stored as starch
• Cellular respiration - sugar -> ATP

  • C6H12O6 -> 6H2O + 6CO2 + ATP
  • Done by plants and animals. Plants make glucose, animals eat glucose.
• Adhesion - attraction of water molecules to something else

  Cohesion - attraction of water molecules to each other
• Root pressure - 

  • 1 - ions get pumped into cells
  • 2 - due to osmosis, water follows
  • 3 - pressure in roots increase from water, pushes water up
  • Water go up because cohesion
