Van Helmont’s Experiment and Photosynthesis
Van Helmont Experiment 5 pound tree 200 pounds of soil Water is added over a 5 year period Predict what will happen
After 5 years Soil: 199lbs, 14 oz. Tree: 169lbs, 3 oz.
lbs.=pounds oz.=ounces
Were you right?
Photosynthesis The process by which a self-feeding
organism can convert light energy into chemical energy in the form of glucose (sugar)
Purpose To change light energy into chemical
energy (stored in the bonds of glucose)
C6H12O6
Photosynthesis: Equation
CO2 + Water Glucose + O2
Carbon Dioxide and Water in the presence of
Light MAKES Glucose and Oxygen
Light
Where does it occur? In chloroplasts
Chloroplasts contain chlorophyll
Light Energy Energy from the sun travels to the earth
Light energy from the sun
Chemical energy in the bonds of glucose (product)
Chemical energy in the bonds of ATP
TRACKING ENERGY
ATP A molecule that stores the energy living
things need to survive
Other photosynthetic organisms Cyanobacteria, algae, and more!
