- PHOTOSYNTHESIS produces GLUCOSE using LIGHT
- PHOTOSYNTHESIS uses ENERGY to change CARBON DIOPXIDE and WATER into GLUCOSE and OXYGEN
- Takes place in - CHLOROPLASTS in GREEN PLANT CELLS - contain PIGMENTS like CHLOROPHYLL that ABSORB LIGHT
- Energy is TRANSFERRED to the CHLOROPLASTS from the environment by LIGHT
- Photosynthesis is ENDOTHERMIC - ENERGY is TRANSFERRED from the ENVIRONMENT in the process.
- Word equation - Carbon Dioxide + Water -(light)-> Glucose + Oxygen
- Symbol Equation (Numbers before are big and others are small (atoms)) 6CO2 + 6H2O -(LIGHT)-> C6H12O6 + 6O2

- PHOTOSYNTHESIS uses ENERGY to change CARBON DIOPXIDE and WATER into GLUCOSE and OXYGEN
- PLANTS USE GLUCOSE IN 5 main ways
- RESPIRATION
- MAKING CELLULOSE - makes PLANT CELL WALLS
- MAKING AMINO ACIDS - Combines with NITRATE IONS, which is then made into PROTEINS
- STORED AS OILS OR FATS - Turned into LIPIDS for storage in SEEDS.
- STORED AS STARCH - For when photosynthesis isn't happening, a cell with lots of glucose would SWELL UP as it would draw in lots of water
- LIMITING FACTORS affect the RATE OF PHOTOSYNTHESIS
- The RATE OF PHOTOSYNTHESIS is affected by intensity of LIGHT, concentration of CARBON DIOXIDE and TEMPERATURE.
- Any of these can become the LIMITING FACTOR-just means they're stopping photosynthesis from happening any FASTER.
- Factors have a COMBINED EFFECT, which one is limiting at a particular time depends on the ENVIRONMENTAL CONDITIONS
- Light - Limiting at NIGHT
- Temperature - Often in WINTER
- Carbon Dioxide - if warm and bright enough the amount of CARBON DIOXIDE.

- CHLOROPHYLL can also be a LIMITING FACTOR
