interactive window will appear. Read the information and answer the questions below.
1. Where does all of the energy come from to sustain life on Earth?
2. During photosynthesis a plant produces oxygen, carbon compounds, ATP, and NADPH. What
is the function for each of those compounds?
3. The energy from sun light is used to split a water molecule. Where do the hydrogen atoms end
up at the end of photosynthesis? What happens to the oxygen that was in the water molecule?
4. What happens to the electrons on a pigment when they are hit by the correct wavelength of
light?
