Plant food

  1. 1. Plant Food
  2. 2. What do plants eat? <ul><li>Discuss with a partner what you think plants eat. </li></ul>
  3. 3. Plant Food Ingredients <ul><li>Water </li></ul><ul><li>Carbon Dioxide </li></ul><ul><li>Light </li></ul><ul><li>End Product: Sugar! </li></ul><ul><li>Carbon dioxide + water + sunlight = sugar + oxygen </li></ul>
  4. 4. But how is the sugar made?
  5. 5. Back up a bit! <ul><li>Photosynthesis takes place in chloroplasts. Remember our first unit lesson about chloroplasts? Chloroplasts contain the chlorophyll that capture light from the sun. </li></ul><ul><li>How many chloroplasts does a plant have? </li></ul><ul><li>Some plants have very few chloroplasts, and others, like tree leaves, can have more than fifty! </li></ul>
  6. 6. Step 1 <ul><li>Light strikes the chlorophyll and energy is used to split apart water molecules into hydrogen and oxygen. </li></ul>
  7. 7. Step 2 <ul><li>Hydrogen joins with carbon from carbon dioxide and forms sugars. </li></ul>
  8. 8. Step 3 <ul><li>Oxygen gas is released into the atmosphere. </li></ul>
  9. 9. How do plants eat the sugar? <ul><li>The plant stores sugars in its tissues and breaks them down. </li></ul><ul><li>When the plant is hungry and needs energy it uses the stored energy. </li></ul>
  10. 10. Why are plants green? <ul><li>Chlorophyll absorbs most colors of light, but not green! When the sunlight hits chlorophyll green light is reflected back to your eye! </li></ul>
  11. 11. Where are the chloroplasts? <ul><li>Leaves hold most of the plant’s chloroplasts. The leaves are the food factory of a plant! </li></ul>=
