Answer AND Explanation:
In spite of its being called the resting phase, many cellular processes take place during this phase. One of the most important of these is chromosomal replication in which each chromosome produces an exact copy of itself. During interphase, the chromosomes are not visible as discrete structures. Instead, they appear as a diffuse tangle of threads called chromatin. Another important event that takes place during interphase is the formation of new cellular organelles, e.g. mitochondria, ribosomes. There is also build up of energy stores which is necessary to drive the mitotic process.
