Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.

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.
