• The conversion of light (radiant) energy into food with the use of chlorophyll.

• Takes place in the chloroplast

• Example organisms: plants, algae, photosynthetic bacteria

Photosynthesis:

Chemosynthesis• the conversion of chemicals into food in the absenceof sunlight• Example organisms: extremeophiles (bacteria, protists)

• Chemical Formula:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

(carbon dioxide) + (water) (glucose)+(oxygen)

Photosynthesis:

Make an illustration of a chloroplast. Be sure to label the thylakoid, stroma, granum, inner membrane and outermembrane.

Factors that affect Photosynthesis:The rate at which photosynthesis occurs is not always the same. The intensity of light, temperature, supply of carbon dioxide, supply of water, and availability of minerals are important factors that affect the rate of photosynthesis in land plants. The rate also varies by species and a plant’s health and maturity. The two graphs below show the effects of light intensity and temperature on the rate of photosynthesis in land plants. These two factors affect many enzymes that control photosynthetic reactions.

1. What does the graph on the left tell about the effect of light intensity on the rate of photosynthesis?2. What happens when light intensity rises above 9000 lumens?3. What adaptive advantages would a plant have if its photosynthetic rate kept increasing with light intensity above 9000 lumens?4. What does the graph on the right tell about the effect of temperature on the rate of photosynthesis?5. What happens when the temperature rises above 33°C?6. What might cause this change?7. What light intensity and temperature levels allow the highest photosynthesis rate?
