In which phase of the cell cycle do cells grow and synthesize new protiens and organelles

The answer is The G1 phase, or Gap 1 phase, is the first of four phases of the cell cycle that takes place in Eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis. G1 phase ends when the cell moves into the S phase of Interphase.
