How do oak trees breathe?

Oak trees, like other plants, breathe through a process called respiration, which occurs in their cells. They take in oxygen from the air and release carbon dioxide, primarily at night when photosynthesis is not occurring. Additionally, during the day, oak trees engage in photosynthesis, where they absorb carbon dioxide and release oxygen, using sunlight to convert carbon dioxide and water into glucose. This dual process of respiration and photosynthesis is essential for their growth and energy production.
