What stage of development do the majority of eukaryotic cells remain in for most of their life?

The majority of eukaryotic cells remain in the interphase stage for most of their life. Interphase is the stage in the cell cycle where cells grow, carry out normal metabolic activities, and replicate their DNA in preparation for division. It is a longer stage compared to the other stages, such as mitosis or meiosis, and typically accounts for around 90% of the cell cycle. During interphase, the cell is actively engaged in various functions essential for its survival, including obtaining nutrients, producing energy, and performing specialized tasks specific to its tissue or organism. Thus, it is the most common stage where eukaryotic cells spend their time.
