interphase is the phase that takes up most of the cells life. In interphase their are three parts: G1, S, G2. Interphase is basically preparing cell for cell division. After iâ¦nterphase takes place, then the cell division takes place with Prophase, metaphase, anaphase, and telephase.
Best Answer: Because cells have to grow, and get energy before they can divide. Interphase is the phase in the cell cycle which would be pretty much the normal activity of the cell.he cell grows during interphase and carries on its normal activities. Many cells never divide and their entire lives are spent in interphase. Even those that are meant to divide-like in a root tip or stem tip-spend the bulk of their time in interphase.
