It Has Been Suggested That Scientists Mimic Photosynthesis by Building

question 71

Multiple Choice

It has been suggested that scientists mimic photosynthesis by building artificial leaves that can respond to electricity from solar cells. The electricity could be applied to the leaves to split water into oxygen and hydrogen. The hydrogen could then be used a fuel. Which of these is the best explanation of how this mimics photosynthesis?

• A) Both this proposed process and photosynthesis store solar energy as electricity for later use.
• B) Both this proposed process and photosynthesis split water into hydrogen and oxygen.
• C) The mimic leaves would have to be green like photosynthesizing leaves in order to respond to light.
• D) Both processes convert electrical energy to light energy.
