1. Photosynthesis Photosynthesis By: Kenzy 8C

2. What is photosynthesis? Process plants use to make their own food Plants’ leaves contain chlorophyll Chlorophyll (green color) makes photosynthesis possible

3. The chlorophyll absorbs the sunlight.

4. Chloroplasts: Sites of Photosynthesis Photosynthesis –Occurs in chloroplasts, organelles in certain plants –All green plant parts have chloroplasts and carry out photosynthesis The leaves have the most chloroplasts The green color comes from chlorophyll in the chloroplasts The pigments absorb light energy

5. In most plants, photosynthesis occurs primarily in the leaves, in the chloroplasts A chloroplast contains: –stroma, a fluid –grana, stacks of thylakoids The thylakoids contain chlorophyll –Chlorophyll is the green pigment that captures light for photosynthesis Photosynthesis occurs in chloroplasts

6. The location and structure of chloroplasts LEAF CROSS SECTION MESOPHYLL CELL LEAF Chloroplast Mesophyll CHLOROPLAST Intermembrane space Outer membrane Inner membrane Thylakoid compartment Thylakoid Stroma Granum StromaGrana

7. The sunlight is combined with water, Carbon Dioxide and nutrients from the soil. CO 2

8. O2O2

9. Plants and animals need each other to survive.

10. Animals including humans make the CO 2 (carbon dioxide) plants need. They (the plants) make the O 2 (oxygen) and food we need.

11. WHY ARE PLANTS GREEN? It's not that easy bein' green Having to spend each day the color of the leaves When I think it could be nicer being red or yellow or gold Or something much more colorful like that…

12. Different wavelengths of visible light are seen by the human eye as different colors. WHY ARE PLANTS GREEN? Gamma rays X-raysUVInfrare d Micro- waves Radio waves Visible light Wavelength (nm)

13. Why are plants green? Reflected light Transmitted light

14. It's not that easy being green… but it is essential for life on earth!
