Detailed explanation-1: -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. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-2: -The Interphase of the eukaryotic cell cycle can be subdivided into the following phases (Figure 7.2. 2). Growth Phase 1 (G1): The cell spends most of its life in the first gap (sometimes referred to as growth) phase, G1. During this phase, a cell undergoes rapid growth and performs its routine functions.

Detailed explanation-3: -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.

Detailed explanation-4: -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-5: -This is one of two ‘gap’ phases in the standard eukaryotic mitotic cell cycle. It is the interval between the completion of DNA synthesis and the beginning of mitosis. Protein synthesis occurs in this phase, following DNA replication in the S phase.
