Activity 2

• CO2 (from air) + H2O (+ minerals from soil) --- chlorophyll to trap solar energy ---> organic food (starch) + O2 (liberated into atmosphere)
• light, chlorophyll, and CO2 are important conditions for photosynthesis
• a control group is important while setting an experiment to be used as a reference to which we compare our results.
• This indicates that light is an important factor for the production of starch by photosynthesis
• This indicates that chlorophyll is an important factor for photosynthesis.
• This indicates that CO2 is an important factor for photosynthesis
