Journal:What three things does a plant need in order to perform photosynthesis?

2. Photosynthesis: Formation of Glucose

3. Takes Place in the Chloroplast
Organelle found in plants and bacteria that has an inner and an outer membrane
The space inside the inner membrane is called the stroma
Inside the stroma there are flat, pancake shaped discs that are called thylakoids

4. Thylakoids Absorb light energy from the sun
Begins the process of photosynthesis

5. Pigments
Substance found within thylakoids that can absorb certain wavelengths (colors) of light and reflects all the other wavelengths
The color you see is the wavelength actually being reflected

6. Chlorophyll
Green pigments found in chloroplasts that absorbs most wavelengths of light, but reflects green and yellow light causing the leaves to appear green

7. Steps of Photosynthesis
Step 1: Light from the sun is absorbed by chlorophyll found in the chloroplasts.
Step 2: Carbon dioxide and water are transported to the chloroplasts
Step 3: The Light Reactions
Step 4: The Dark Reactions

8. Light Reactions Occurs in the thylakoids
Sunlight, Carbon Dioxide, and Water react to form ATP and NADPH, which then go to the stroma where the dark reactions occur.
Requires sunlight to be present

9. Dark Reactions Also known as the Calvin Cycle
ATP and NADPH from the light reactions leave the thylakoids and move to the stroma, where they combine with carbon dioxide to form sugar in the form of glucose (C6H12O6)
Does not require sunlight to be present

11. Factors that Affect Photosynthesis
Light Intensity
Carbon dioxide concentration
Temperature
