In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.
The correct answer to this question : <span>Carbon dioxide, Nitrous Oxide, Methane</span>
An artificial leaf could replicate photosynthesis but instead it would also be artificial which then produces hydrogen fuel that will be energy efficient and carbon neutral. hope this helps.
