By duplicating the cell content, DNA replication and synthesis of substances such as proteins needed during M phase of cell cycle.
Explanation:
Interphase prepares the cell for cell division by duplicating the content of the parent cell.
The G1 phase of interphase is marked by duplication of cell organelles and other cellular components except the DNA. There is synthesis of enzymes needs for DNA replication and synthesis of protein needs for cell division.
The S phase of interphase includes replication of DNA. This is done so that the daughter cells could obtain exact copies of the DNA present in the parent cell. Both G1 and G2 of interphase are the stages of cell growth.
