Question

what is the role of CO2 and H2O in the process of photosynthesis​

Answer 1

Answer:

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. ... The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

Answer 2

Answer: Photosynthesis takes water (H2O) plus carbon dioxide (CO2) and using solar energy, turns that into various sugars. Let’s take glucose (C6H12O6), for example: It takes 6 molecules of CO2 and six of H2O - resulting in one molecule of glucose. Because there were 18 oxygen atoms involved and the sugar only has 6 of them, the remaining 12 oxygen atoms from six O2 molecules. Normal animal and night-time plant respiration does pretty much the reverse - turning oxygen and sugars (and other stuff) back into CO2 and water. The energy that the plant locked away into the sugar becomes the energy to power our activity - and in return, we make more CO2 for it to turn back into food.
