Detailed explanation-1: -During the second gap phase, or G 2start subscript, 2, end subscript phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.

Detailed explanation-2: -The last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

Detailed explanation-3: -G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase. The cell synthesizes proteins and continues to increase in size. Note that the G in G2 represents gap and the 2 represents second, so the G2 phase is the second gap phase.

Detailed explanation-4: -If a cell passes the G1 checkpoint, it enters S stage (synthesis stage) in which DNA replication occurs. After successful DNA synthesis, the cell enters G2 stage where the cell continues to grow in size, duplicating organelles and cytosol.
