Detailed explanation-1: -Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter-means between, so interphase takes place between one mitotic (M) phase and the next.

Detailed explanation-2: -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. During the G1 phase, cells are extremely metabolically active.

Detailed explanation-3: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.

Detailed explanation-4: -Thus Interphase is the longest phase in the life of a cell. Interphase: This is the period between two successive mitotic divisions. It is a period of active synthesis and intense growth.

Detailed explanation-5: -A cell spends the longest in Interphase due to the following reasons: Cell growth takes place during this period. DNA synthesis takes place which is in preparation for pre-mitotic division. Replication of chromosomes takes place.
