Plants require oxygen to breakdown glucose in the mitochondria. The total amount of energy released is very high. The end products formed are carbon dioxide, water and energy. The process of cellular respiration is a redox reaction. The oxygen molecule is reduced and glucose oxidised. Plants undergo respiration to provide energy that is used during photosynthesis. The manufacture of food by plants requires energy. Highly active and dividing cells have more mitochondria with abundant cristae to provide enough energy.
