Detailed explanation-1: -The G1 phase is the longest in the cell cycle. It’s the beginning of the interphase. The cell prepares for division during the G1 phase.

Detailed explanation-2: -The interphase is the longest phase of the cell cycle because it is the stage during which all the preparation for cell division takes place.

Detailed explanation-3: -G1 is typically the longest phase of the cell cycle. This can be explained by the fact that G1 follows cell division in mitosis; G1 represents the first chance for new cells have to grow. Cells usually remain in G1 for about 10 hours of the 24 total hours of the cell cycle.

Detailed explanation-4: -The longest stage of interphase is S; cells typically spend about 7 hours in this stage. The shortest stage of interphase is G2 (3 hours), although the shortest stage of the entire cell cycle is mitosis (1 hour).
