  1. Photosynthesis

  2. Photosynthesis Definition • Process where radiant energy (from the sun) is used to turn water and carbondioxide into glucose and oxygen. • It is one example of how people and plants are dependent on each other in sustaining life.

  3. Ingredients needed for Photosynthesis:

  4. Carbon Dioxide Gas • Released by animals, including us, and absorbed through the stomata in the leaves. • Carbon Dioxide's formula is CO2.

  5. Water • It is absorbed through the roots. • H2O is the formula for water.

  6. Radiant Energy (Sunlight) • Radiant energy is the main part of the process. • Sunlight is absorbed through the leaves when it is trapped by the chlorophyll in the chloroplasts. • Without sunlight, the plants would not give off oxygen or have energy.

  7. Chlorophyll • Chlorophyll is the chemical in chloroplasts and gives plants their green color. • Chloroplasts are the cell bodies, or organelles, inside plant’s leaves.

  8. End Products:

  9. Glucose • Glucose is made by photosynthesis, and it provides the plant it’s own food. • As the plant grows, it breaks down stored glucose to release the energy.

  10. Oxygen • Oxygen is a by-product that plants release during photosynthesis which provides a vital need of animals.

  11. Scientists show this as a chemical reaction: Carbon Dioxide + Water + Sunlight and Chlorophyll = Glucose and Oxygen6CO2 + H2O + Sunlight and Chlorophyll = C6H12O6 + 6O2
