Plant parts and photosynthesis
- 1. Done By: Abir Berro Grade level : 4 Prepared to: Dr. Rima Malek Year: 2013 - 2014
- 2. In this activity you will: • Learn about the plant parts. • Learn about the process of Photosynthesis.
- 3. 1 2 3 4
- 4. Fruits and seeds form inside.
- 5. • Stems help hold plants up.
- 6. • Where the plant makes food.
- 7. 4) Roots: • Roots take up water and other materials that plants need from the soil. • Roots also hold plants in the soil.
- 9. Fruits and seeds form inside
- 10. Take in water and nutrients from the soil
- 11. Carry water and nutrients from the roots to the rest of the plant
- 12. Hold the plant in the ground
- 13. Where the plant makes food
- 14. Holds up the leaves
- 15. Roots stem leaf flower roots leaf stem
- 17. What is photosynthesis? • It’s a Process by which plants make their own food.
- 19. 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
- 21. 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
- 22. The chlorophyll absorbs the sunlight. Plants’ leaves contain chlorophyll Chlorophyll (green color) Chlorophyll is needed for photosynthesis
- 23. The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen. Sugar + Air O2
- 25. 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
- 27. 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
- 28. Plants and animals need each other to survive.
- 29. Animals including humans make the CO2 (carbon dioxide) plants need. They (the plants) make the O2 (oxygen) and food we need.
- 30. Plants Need Oxygen to make photosynthesis: True False
