As a whole, plants tend to release more oxygen than carbon dioxide into the environment, but the ratios of gases differ at various times of the day. plants tend to take in more carbon dioxide during the day and release more oxygen. at night, they tend to take in more oxygen and excrete more carbon dioxide. how does the model support this phenomenon?

During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.

its the cell wall and the they are unique to plant

what are the options? add them, then i will be glad to .
