WebbThe basic chemical reaction for oxygenic photosynthesis is: CO 2 + 2H 2 O + photons → [CH 2 O] + O 2 + H 2 O. During photosynthesis, one molecule of carbon dioxide and 2 molecules of water are converted into molecular oxygen and some carbohydrate. Creating organic compounds from inorganic carbon is known more generally as “carbon fixation.”.

Photosynthesis systems … Webb3 juli 2024 · Photosynthesis occurs in the green tissue of plants. This is primarily in the leaves, although photosynthesis also occurs in stems. Roots aren't exposed to light, so there's no point for a plant to put chlorophyll in them. Flowers serve a reproductive purpose, so again, there's no reason for plants to use them for photosynthesis.
