photosynthesis

• why do plants photosynthesise

  to make food from glucose
• equation for photosynthesis 


  carbon dioxide + water = glucose + oxygen
• symbol equation for photosynthesis

  6CO2+6H2O=C6H12O6+6O2
• glucose is stored by plants as starch
• the test to see if a plant is photosynthesising


  iodine turns the leaf blue blacm
• why is photosynthesis endothermic

  because energy is transferred from the environment (sun) during photosynthesis
• what do plants make glucose from


  sunlight
• factors which affect the rate of photosynthesis

  1. temperature
  2. light intensity
  3. CO2 concentration
