Cellular respiration would produce less energy when plant were to lose much of its chlorophyll.
Plants can actually live longer without photosynthesis than they can without respiration. Some plants survive half the year without performing photosynthesis, but if they stop performing cellular respiration, even for a minute, they would be dead where they stand.
During photosynthesis, plants absorb sunlight and carbon dioxide from the air. Through a series of steps, much like cellular respiration, they convert these reactants into the products oxygen and glucose. The plants then can use the oxygen and glucose to make ATP in cellular respiration. The rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide is produced during respiration.
