1. Photosynthesis

2. Process used to convert light energy into chemical energy, glucose
Photosynthesis
Process used to convert light energy into chemical energy, glucose
Chemical reaction -
6CO2 + 6H2O sunlight C6H12O6 + 6O2

3. Reactants (start) – CO2 and H2O
Products (finish) - C6H12O6 (glucose) and O2
Chlorophyll must be present

4. These are the organisms that carry out photosynthesis:
Plants
Algae
Some protists
Some bacteria

5. Photosynthetic Organisms

6. Factors affecting photosynthesis
Shortage of water can slow or stop photosynthesis
Plants in dry environments must reduce water loss
Photosynthesis depends on enzymes that work best between 00C(32oF) and 350C (95oF)

7. Rate of photosynthesis relates directly to amount of light
More light = more or faster photosynthesis
Less light = less or slower photosynthesis
