Photosynthesis From Sun to Cell

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).

Presentation Transcript

  1. PhotosynthesisFrom Sun to Cell

  2. 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)

  3. 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.

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

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

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

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

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