Transcript

NARRATOR: The electrons lost from chlorophyll during photosynthesis have to be replaced. Plants do this by splitting water molecules and using electrons from hydrogen, leaving oxygen as waste product.

When water plants like Elodea are photosynthesizing, it is easy to see the bubbles of oxygen gas being released.
