Read the paragraph from the section "Stages of Photosynthesis."
During photosynthesis, chlorophyll
takes in energy from the sunlight, and
this starts a chain of steps that result in
the production of ATP and NADPH. In
photosynthesis, water molecules
(H20) have to split. When the water
molecules split, they release oxygen
through the stomata.
Why did the author use the word "release?"
