PHOTOSYNTHESIS

1. Defined § Photosynthesis is the process that most producer organisms (organisms that make their own food) use to change light energy into chemical energy (food)

1. Defined § Photosynthesis is the process that most producer organisms (organisms that make their own food) use to change light energy into chemical energy (food) § Requires special pigments, organelles, and enzymes

1. Defined § Photosynthesis is the process that most producer organisms (organisms that make their own food) use to change light energy into chemical energy (food) § Requires special pigments, organelles, and enzymes § Find photosynthesis in plants, algae, and other producer organisms

2. Process

2. Process § Carbon Dioxide + Water + Light Energy § = § Sugar + Oxygen

2. Process § Carbon Dioxide + Water + Light Energy § = § Sugar + Oxygen

3. Required Elements

3. Required Elements

3. Required Elements § Pigments – colored substances that absorb light energy…light energy changes into chemical energy (food)

3. Required Elements § Pigments – colored substances that absorb light energy…light energy changes into chemical energy (food) § Chlorophyll – primary pigment used in photosynthesis
