Solution

During $G_{1}$ phase, cell grows in size by increasing the volume of the cytoplasm. RNA and proteins are synthesised. Organelles like the chloroplast and mitochondria divide.
After the $G_{1}$ phase, the cells may or may not enter a resting or dormant phase called the $G_{0}$ phase. During this phase, no activities pertaining to division takes place in the cell.
Then the cell enters the S phase, during which the DNA replication takes place.
S phase is followed by the $G_{2}$ phase, in which the cells synthesises more proteins and gets ready to enter the mitotic phase.
