Why do plants need to take in oxygen?

Answer 1

The first part got removed, after I had answered this question, the author had it kind of in reverse, so that why I said, this.

Sorry, but thats kind of in reverse, plants do not absorb oxygen, they produce oxygen, we

breath the oxygen, we also produce carbon dioxide, which is what we ex-hale, and the plants, absorb the carbon dioxide, But yes, after all said and done, we depend on plants, for the oxygen they produce, especially trees , and the rain forests. So thank you God, for makeing a world that works, and thank you plants, for makeing oxygen.

Answer 2

Plants require oxygen for cellular respiration, a process that breaks down glucose to produce energy. While plants perform photosynthesis to create glucose and oxygen during the day, they still need to take in oxygen to generate the energy needed for growth, metabolism, and other physiological processes, particularly during the night when photosynthesis isn't occurring.
