Question

Why does a potted plant die when over-watered?

Accepted Answer

Just like us, plants require water to survive. Through their roots, they take in water, which they then use for several vital functions, including breathing. Although plant respiration differs from animal respiration, it is still essential to a plant's life.
Through microscopic openings on their leaves known as stomata, plants breathe in oxygen from the surrounding air during respiration. Similar to how our cells use oxygen to make energy, the plant's cells use this oxygen to do the same.
The cracks between the soil particles are filled with extra water when a plant is overwatered, preventing air from getting to the roots. The roots are so depleted of oxygen.
The plant's cells cannot properly conduct respiration if there is not enough oxygen available. Because of this, the plant is unable to produce enough energy, which is necessary for its growth, development, and general health. Due to the excess wetness and lack of oxygen, the plant's roots may begin to rot, causing severe harm.
