Its a chemical change. Leaves breathe in carbon dioxide. They use it to carry out the process of photosynthesis that is preparation of food for growth.
Chemical changes involving salts, water, carbon dioxide take place in the presence of sunlight that results in the liberation of oxygen into the atmosphere.
At night however in the absence of sunlight it breathes in oxygen to prepare food, since photosynthesis is not possible due to absence of sunlight.
