No, plants do not get oxygen at night. During the day, plants engage in photosynthesis, a process in which they use carbon dioxide and sunlight to produce glucose and oxygen. However, photosynthesis cannot occur in the absence of sunlight, so during the night, plants switch to a different process called respiration.

Respiration in plants is similar to respiration in animals. It involves the breakdown of glucose to release energy for various cellular activities. In this process, plants take in oxygen and release carbon dioxide, just like animals do. This is why plants are considered to be aerobic organisms that require oxygen for respiration.
However, it is important to note that during the night, the rate of respiration in plants is usually lower than during the day. This is because they do not require as much energy during this period. As a result, the amount of oxygen plants consume at night is relatively small compared to the oxygen they produce during the day through photosynthesis.
In summary, while plants do not get oxygen directly from the atmosphere at night, they still require oxygen for the process of respiration. The oxygen they need is sourced from the oxygen they produce during the day or from any stored oxygen within their cells. Therefore, plants are not dependent on oxygen from the external environment during the night.
