G1 is the longest phase of the cell cycle which is a part of interphase

Explanation:

75% of the time of a cell is spent in interphase

The reason a cell spends most of its time in the G1 phase is that G1 is the first chance or the beginning of a new cell to grow. This can be related to when babies are born as the longest phase is the growth of the embryo/fetus.

Similarly, the cell has just begun in interphase, therefore, required the most amount of time to create everything necessary for the rest of the process.

We can estimate that the time spent in this phase is approximately 10 1/2 hours
