Ppt Ecol Photosynthesis

  1. 1. Photosynthesis<br />EQ:What resources do plants need to make food?<br />How does plants and animals help each other?<br />Warmup Review:<br />What does an energy pyramid represent? Why does energy run out by the time it gets to a 3rd level or 4th level consumer?<br />
  2. 2.
  3. 3. Photosynthesis is like Baking<br />Make a cake<br />Ingredients<br />Eggs<br />Milk<br />Flour<br />Oven/Pan<br />Heat<br />Gives energy<br />Cake mix turns to cake. <br />Make Sugar(glucose)<br />Ingredients<br />Carbon Dioxide<br />Water<br />Plant/Chlorophyll<br />Sunlight<br />Gives energy<br />Ingredients are turned into SUGAR!!(glucose)<br />
  4. 4. Photosynthesis<br />Photosynthesis is a chemical reaction just like cake! <br />What do we need for photosynthesis?<br />Ingredients:<br />Water<br />Carbon Dioxide<br />ENERGY!!<br />Sunlight<br />
  5. 5. Sugar is like a battery<br />When an organism needs energy, they can burn sugar. <br />
  6. 6. Oxygen<br />When a plant makes sugar there is leftovers. <br />Very important for us!<br />Making sugar leaves extra oxygen which plants breathe out. We breathe in. <br />
  7. 7. Oxygen burns<br />Why do we need oxygen?<br />To BURN Sugar<br />We burn sugar for energy. <br />Burning sugar makes Carbon Dioxide<br />
  8. 8. Carbon Dioxide<br />Who needs carbon dioxide?<br />Why do plants need carbon dioxide?<br />How do animals help plants?<br />How do plants help animals?<br />
  9. 9. Summary <br />Sunlight <br />Carbon Dioxide<br />Water<br />Oxygen<br />Sugar<br />
  10. 10. Carbon Dioxide-Oxygen Cycle<br />
  11. 11.
  12. 12. Review<br />What two chemicals do plants need to make sugar?<br />What do plants need from sunlight to be able to turn chemicals into food?<br />What do plants breathe out when they are done with photosynthesis?<br />How do animals get the sugar?<br />Why do animals need the sugar?<br />What do the animals release when they breathe out?<br />
  13. 13. Draw a diagram with a plant and an animal. Include the following things. <br />Show the plant taking in Carbon Dioxide and water, Sunlight<br />Show what the plant releases<br />Show what the animal takes in<br />Show what the animal releases. <br />Show sugar<br />
