8-2 Photosynthesis: An Overview Pg. 204

A. Investigating Photosynthesis 1. Van Helmont’s Experiment- Measures the water intake of plants and how much weight they gained. Conclusion: Plants gain most weight from water!

A. Investigating Photosynthesis 2. Priestley’s Experiment- Used bell jar, candle, and plant to find that plants release oxygen. Conclusion: Plants release oxygen!

A. Investigating Photosynthesis 3. Jan Ingenhousz- Found that aquatic plants produce oxygen bubbles when they are in the light but not in the dark. Conclusion: Plants need light to grow!

Materials Problem Conclusion Van Helmont Priestley Ingenhousz

B. The Photosynthesis Equation 1. Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into high energy sugars and oxygen.

B. The Photosynthesis Equation

B. The Photosynthesis Equation Carbon Dioxide, Water, Sunlight, Glucose, Oxygen

C. Light and Pigments 1. Photosynthesis also requires light and chlorophyll, molecule in chloroplasts. 2. The main pigment in plants is chlorophyll.

Exit Ticket Why is photosynthesis important? Using the following words, write a paragraph: Autotroph Sunlight Energy Nutrients Water Chlorophyll Oxygen Glucose Carbon Dioxide
