Plants are living organisms that, like animals, require oxygen to survive. Oxygen is essential for the process of respiration, which allows plants to produce energy from the food they make through photosynthesis. During respiration, plants convert glucose (a sugar produced during photosynthesis) into energy through a series of chemical reactions that involve the breakdown of glucose and the release of energy. Oxygen is required for these reactions to take place, so if a plant does not have access to oxygen, it will not be able to produce the energy it needs to survive.
There are some plants that can survive for short periods of time in low-oxygen environments, such as certain aquatic plants that can grow in stagnant water. However, these plants have adapted specialized mechanisms to cope with low-oxygen conditions and are still ultimately dependent on oxygen to survive.
In general, it is not possible for a plant to survive indefinitely without oxygen. If a plant is not getting enough oxygen, it will eventually die. This is why it is important to provide plants with enough light and air circulation, as these factors help to ensure that the plant has access to the oxygen it needs to survive.
