1. Photosynthesis
*Photo=light synthesis= to make…Using light to make the plants food…Also helps us remember the two stages of photosynthesis photo=light reactions synthesis- calvin cycle that makes our end product

2. What you know.
Photosynthesis is the process by which plants make their food…Carbohydrates….Glucose.
Photosynthesis takes light energy and converts it into biologically usable chemical energy stored in glucose by breaking apart and rearranging carbon dioxide and water.

3. Where does Photosynthesis happen?
It takes place inside the CHLOROPLAST, with dozens of them found in the cells of each leaf
Inner Membrane
Outer Membrane
Stroma
Intermembrane
Space
-All green parts of the plant including leaves, stems, unripened fruit have chloroplast
-Talk about it and then have students stop and draw on a folded computer paper. Thylakoids, Granum, Stroma
-Chlorophyll pigment found in thylakoid membranes make green
Thylakoid
Granum

4. Law of Conservation of Energy
Energy is not created or destroyed, only converted/transfered!!!

5. Light Energy
Light is both a particle and a wave Each color is a different wavelength Shorter wavelength = more energy

6. -Light from the sun is really all colors of the rainbow…ROYGBIV

7. Colors and Pigments
Pigments are molecules that can absorb some wavelengths and reflect others. Example: Chlorophyll Photosystems: Arrangement of chlorophyll & proteins used to collect/absorb the suns energy What color is it really? Explain color in your own words:

8. Law of Conservation of Matter
Matter is not created or destroyed, only rearranged!!! How is this true in photosynthesis?

9. Living Things and Matter
Plants and animals will do 3 things with their matter: 1) Rearrange it to build cell/body structures 2) Break it apart to release energy 3) Discard what they don’t use

10. What happens to the glucose?
Glucose is: 1) Broken apart in the mitochondria and used to make lots of easy to use ATP energy or 2) Chained together to make the plants body 3) Eaten by other organism and used for their energy

11. Matter and Energy
Matter can trap and transfer energy Examples in photosynthesis… Electron carriers Pigments

12. Factors Affecting Photosynthesis
1) Light Intensity
in light = ____ in the rate of photosynthesis
***Warning:____________________
2)Temperature –
best between 0 C and 35 C
If the temperature is too higher or too low,
this changes the shape of the
enzymes involved in photosynthesis.
3) Carbon Dioxide Levels
in CO2 = ____ in the rate of photosynthesis
