Identify 2 of the vital gases that are exchanged between leaf tissues and the outside environment. describe the processes that produce these gases

1.Oxygen through the process of photolysis
photolysis occur during the day, in this process water molecule is split by light through the equation
2H20+4H+ +4e-+o2 and oxygen is given off through this process, it occurs mostly in the light stage of photosynthesis
2.carbon dioxide through the process of respiration in plants. Mostly at night, plants take in oxygen and give out carbon dioxide just like animals
