Plant parts and photosynthesis

  1. 1. Done By: Abir Berro Grade level : 4 Prepared to: Dr. Rima Malek Year: 2013 - 2014
  2. 2. In this activity you will: • Learn about the plant parts. • Learn about the process of Photosynthesis.
  3. 3. 1 2 3 4
  4. 4. Fruits and seeds form inside.
  5. 5. • Stems help hold plants up.
  6. 6. • Where the plant makes food.
  7. 7. 4) Roots: • Roots take up water and other materials that plants need from the soil. • Roots also hold plants in the soil.
  8. 8. NAME THE PLANT PARTS
  9. 9. Fruits and seeds form inside
  10. 10. Take in water and nutrients from the soil
  11. 11. Carry water and nutrients from the roots to the rest of the plant
  12. 12. Hold the plant in the ground
  13. 13. Where the plant makes food
  14. 14. Holds up the leaves
  15. 15. Roots stem leaf flower roots leaf stem
  16. 16. Leaves flowerroots stem
  17. 17. What is photosynthesis? • It’s a Process by which plants make their own food.
  18. 18. Plants need energy to grow • Plants need energy to grow • Plants get energy from the sun • Plants use energy to carry on the process of photosynthesis
  19. 19. Plants need sunlight for photosynthesis • Cells in the plant trap light energy from the sun • Plants use the sun’s energy to change carbon dioxide and water into sugar • The plant uses the simple sugars to help it grow
  20. 20. The chlorophyll absorbs the sunlight. Plants’ leaves contain chlorophyll Chlorophyll (green color) Chlorophyll is needed for photosynthesis
  21. 21. The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen. Sugar + Air O2
  22. 22. Plants have tiny holes in the bottom of each leaf The tiny holes let air go in and out of the leaf Plants use a gas in the air called carbon dioxide Plants release oxygen back into the air CO2
  23. 23. Plants need water for photosynthesis • Plants get water from the soil • Roots bring water from the soil to the plant • Water is needed for the cells of the plant to carry on photosynthesis
  24. 24. Plants and animals need each other to survive.
  25. 25. Animals including humans make the CO2 (carbon dioxide) plants need. They (the plants) make the O2 (oxygen) and food we need.
  26. 26. Plants Need Oxygen to make photosynthesis: True False
  27. 27. Soil rain leaf flower
  28. 28. Sunlight WaterStarch SoilOxygen CO2
