Photosynthesis From Sun to Cell

All energy that fuels life comes from the sun. In photosynthesis, plants capture light energy from the sun and change it into food. Consumers would not survive without green plants. (starts food chains, gives us oxygen)

Plant cells have chloroplasts which contain pigments called chlorophyll that are green. Chlorophyll captures the light energy from the sun. Plants change the energy into food.

Chemicals Involved in Photosynthesis C02 = Carbon Dioxide H2O = Water C6H12O6 = Glucose O2 = Oxygen

Chemical Equation for Photosynthesis 6CO2 + 6H2O  C6 H12 O6 + 6O2

Raw Materials ( Reactants) for Photosynthesis 1. Sunlight 2. Water H2O 3. Carbon Dioxide CO2 4. Chlorophyll

Products of Photosynthesis 1. Glucose ( C6H12O6) 2. Oxygen (O2)

Autotrophs and Heterotrophs Autotrophs – organisms that make their own food ( producers ) Heterotrophs – organisms that eat other organisms to obtain energy ( consumer)
