1. 1 Chapter 10 part II Photosynthesis

2. 2 Outline What is Photosynthesis? Properties of light What are waves? Useable light colors Chloroplast structures Light Reaction Dark Reaction

3. 3 What is Photosynthesis?

4. 4 Chloroplast Mitochondria

5. 5 Photosynthesis overview Plants are able to synthesis glucose by using carbon dioxide gas and water as the raw materials. Sunlight is used as the energy to power this transformation This chemistry takes place in the chloroplast of the plant cell. A special chemical called Chlorophyll makes this possible.

6. 6 Properties of Sunlight Sunlight is a form of energy Energy travels in electromagnetic waves that vary in size Colors are nothing more then different size electromagnetic waves. Objects that exhibit a color have that color because it is the wave that is reflected.

7. 7 What is a wave?

8. 8 Electromagnet spectrum

9. 9 Light and plants Plants don’t really need green light because it’s the light wave that is reflected off the plant Colors ( wave lengths) of red, blue, violet are more important to most plants.

10. 10 Action spectrum

11. 11 What traps the light? Inside the chloroplast are chlorophylls that are able to trap the energy from the electromagnetic waves. This trap energy is used to combine certain elements into a compound

12. 12 Cholorplast

13. 13 Photosynthesis- Light reaction Each type of Chlorophyll will absorb a different wave length.
