Sect 12.1

  1. 1. 6 th Grade Science Chapter 12 Plant Processes Notes Section 12.1 Keukenhof Gardens - Holland
  2. 2. <ul><li>What raw materials do leaves take in? </li></ul><ul><li>Leaves take in carbon dioxide that is used in photosynthesis. </li></ul><ul><li>What are the waste products of photosynthesis and respiration? </li></ul><ul><li>Oxygen is the waste product of photosynthesis. Carbon dioxide is the waste product of respiration. </li></ul>Key Questions 1 Keukenhof Gardens - Holland
  3. 5. <ul><li>Where is most of the plant’s food made? </li></ul><ul><li>Most of the plant’s food is made in the palisade layer. </li></ul><ul><li>Why are chloroplasts green? </li></ul><ul><li>Chloroplasts are green because they contain the green pigment chlorophyll. </li></ul>Key Questions 2 The Tadpole Galaxy Keukenhof Gardens - Holland
  4. 7. In fall, the chlorophyll in some leaves breaks down and the leaves change color as other pigments become visible.
  5. 8. <ul><li>What is a pigment? </li></ul><ul><li>A pigment is a substance that reflects a particular part of the visible spectrum. Green leaves absorb all the colors of the rainbow except green. </li></ul><ul><li>Where is the plant’s excess sugar stored? </li></ul><ul><li>Excess sugar produced in the leaves of a carrot are stored in the orange root. </li></ul>Key Questions 3 The Sombrero Galaxy Keukenhof Gardens - Holland
  6. 10. <ul><li>Photosynthesis occurs only in a carrot plant’s lacy green leaves. </li></ul><ul><li>Excess sugar produced in the leaves is stored in the familiar orange root that you and many animals eat. </li></ul>
  7. 11. <ul><li>Besides light, plants also need the raw materials carbon dioxide and water for photosynthesis. </li></ul><ul><li>The overall chemical equation for photosynthesis is shown. </li></ul>
  8. 12. <ul><li>Reactions that don’t need light are called the light-independent reactions of photosynthesis. </li></ul><ul><li>The light energy trapped during the light-dependent reactions is used to combine carbon dioxide and hydrogen to make sugars. </li></ul><ul><li>One important sugar that is made is glucose. The chemical bonds that hold glucose and other sugars together are stored energy. </li></ul>Light-Independent Reactions
  9. 13. <ul><li>During light-dependent reactions, chlorophyll and other pigments trap light energy that eventually will be stored in sugar molecules. </li></ul><ul><li>Light energy causes water molecules, which were taken up by the roots, to split into oxygen and hydrogen. </li></ul><ul><li>The oxygen leaves the plant through the stomata. </li></ul><ul><li>Hydrogen produced when water is split is used in photosynthesis reactions that occur when there is no light. </li></ul>Light-Dependent Reactions
  10. 14. <ul><li>What is the main form of food for plant cells? </li></ul><ul><li>Glucose is the main form of food for plant cells and the basis of a plant’s structure. </li></ul><ul><li>What is respiration? </li></ul><ul><li>Respiration is a series of chemical reactions that breaks down food molecules and releases energy. </li></ul>Key Questions 4 Keukenhof Gardens - Holland
  11. 17. <ul><li>Describe how gasses enter and exit a leaf. </li></ul><ul><li>Explain why photosynthesis and respiration are important. </li></ul><ul><li>Identify what must happen to glucose molecules before respiration begins. </li></ul><ul><li>Compare and contrast the number of organisms that respire and the number that photosynthesize </li></ul><ul><li>Humidity is water vapor in the air. Infer how plants contribute to humidity. </li></ul>Questions Section 12.1 Keukenhof Gardens - Holland
