  1. Warm Up3/18/19 Welcome back! Write 1 paragraph to summarize what you enjoyed most about spring break.

  2. Homework Textbook Pages 226-237 Due Thursday

  3. Foldable 2 sheets of paper, fold as directed Photosynthesis Cellular Respiration Where Where Purpose Purpose Formula Formula Must include descriptions & pictures

  4. Photosynthesis Grade 7 Science

  5. What is photosynthesis? • Process plants use to make their own food • Some plants cells contain chlorophyll • Chlorophyll (green color) makes photosynthesis possible • It occurs in the chloroplast

  6. The chlorophyll absorbs the sunlight.

  7. The sunlight is combined with water, Carbon Dioxide and nutrients from the soil. CO2

  8. 6CO2 + 12H2O + light energy  C6H12O6 + 6O2 The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen. Sugar + Air O2

  9. Equation for Photosynthesis 6CO2 + 6H2O + Sunlight  C6H12O6 + 6O2 Reactants  Products

  10. Reactants Reactants are what you start with in a chemical reaction. These are the substances that enter into a chemical reaction.

  11. Products • Products are what you end with in a chemical reaction. • Products are substances which form as a result of a chemical reaction.

  12. Plants and animals need each other to survive.

  13. Animals including humans make the CO2 (carbon dioxide) plants need.They (the plants) make the O2 (oxygen) and food we need.

  14. Cellular Respiration • The process by which cells use oxygen to produce energy from food. • It occurs inside the Mitochondria

  15. Cellular RespirationEquation C6H12O6 + 6O2  6CO2 +6H2O + Energy (ATP) Reactants  Products

  16. Science Closure3/18/19 What does a plant need to make sugar through photosynthesis? • soil, water, and oxygen • carbon dioxide, sunlight, and soil C. oxygen, sunlight, and soil D. sunlight, water, and carbon dioxide

  17. Closure What part of a plant can perform photosynthesis? A. only the leaves B. only the stem C. only the roots D. any cell with chlorophyll
