In photosynthesis carbon dioxide (CO2) and water (H2O) r â¦ eact chemically and transform into glucose (C6H12O6) and oxygen (O2). This process is driven by the energy of sunlight. An energy then bound chemically in the glucose, which is a primitive type of sugar. to recap: 4 things are needed.or photosynthesis to occur a plant needs water (H2o) carbon dioxide (what we breathe out) and sunlight. Without these things a plant cannot complete photosynthesis. Hope th â¦ is helps.
