As a botanist with a keen interest in plant physiology, I can provide you with a detailed explanation regarding the balance of oxygen and carbon dioxide production in plants.
Plants, through the process of photosynthesis, are indeed the primary producers of oxygen on Earth. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, storing it in the form of glucose and releasing oxygen as a byproduct. This process is fundamental to life on Earth as it not only provides the oxygen we breathe but also the organic compounds that form the basis of the food chain.
However, it's crucial to understand that plants also respire. Respiration is a metabolic process that occurs in all living cells, including those of plants. During cellular respiration, plants, like animals, consume oxygen and release carbon dioxide. This is a continuous process that occurs 24/7, regardless of whether it is day or night.
The key point here is the balance between photosynthesis and respiration. During the day, when light is available, the rate of photosynthesis in plants is much higher than the rate of respiration. This is because photosynthesis requires light energy, which is abundant during daylight hours. As a result, plants produce more oxygen than they consume, leading to a net release of oxygen into the atmosphere.
At night, when there is no light, photosynthesis ceases, but respiration continues. Consequently, plants consume oxygen and release carbon dioxide during the night. However, the amount of carbon dioxide released during the night is typically less than the amount of oxygen produced during the day. This is because the rate of respiration is generally lower than the rate of photosynthesis when light is available.
It's also important to note that not all cells in a plant are capable of photosynthesis. Only the cells that contain chloroplasts, which are primarily found in the leaves, can perform photosynthesis. Other cells, such as those in the roots or the interior of stems, do not contain chloroplasts and therefore cannot photosynthesize but do respire.
The concentration of carbon dioxide in the atmosphere is indeed increasing due to human activities, but it is still significantly lower than the concentration of oxygen. The Earth's atmosphere is composed of approximately 21% oxygen and around 0.04% carbon dioxide. Despite the increase in carbon dioxide levels, the balance of gases in the atmosphere is largely maintained by the continuous process of photosynthesis and respiration by plants.
In summary, while plants do produce carbon dioxide through respiration, they produce far more oxygen through photosynthesis, especially during daylight hours. The overall effect of plants on the atmosphere is a net increase in oxygen, which is essential for the survival of all aerobic organisms, including humans.

So overall, even though the concentration of carbon dioxide is increasing, it's levels are many times lower than oxygen. Here's the thing, plants are doing cellular respiration all day, too! ... All of the cells in a plant do cellular respiration, but not all do photosynthesis. Look at a tree.
