TB pg. 11 SUNLIGHT OXYGEN CARBON DIOXIDE GLUCOSE WATER GLUCOSE ENERGY
3
TB pg. 11 ALL living organisms need energy to survive.
In photosynthesis: green plants produce glucose (food). Carbon dioxide + Water Glucose + Oxygen CO2 + H2O C6H12O6 + O2 This glucose is stored as potential energy. Chlorophyll Sunlight Chlorophyll Sunlight TB pg. 11
4
The energy can be released by the plant, in a series of chemical reactions.
In respiration, plants and animals break down glucose and release carbon dioxide, water and energy. Glucose oxygen carbon dioxide + water + energy C6H12O O2 CO H2O + energy Write down TB pg. 11

During photosynthesis, plants use energy from the Sun to produce .
During respiration food is broken down and is released. TB pg. 11
