Expert Answer:

(i) In plants, each part can independently take in oxygen from the air and give out carbon dioxide. In the cells, the oxygen is used to break down glucose into carbon dioxide and water.

(ii) If a potted plant is over-watered for a long time, then the plant may die because too much water expels all the air from in-between the soil particles and water is not available for aerobic respiration.
