Final answer:
Most eukaryotic cells spend the majority of their life cycle in interphase, which includes G1, S, and G2 phases. Studies show that if 100 cells are examined, around 93 would typically be in interphase, as only approximately 7% of cells are in the mitotic phase at any given time.
Step-by-step explanation:
During interphase, most eukaryotic cells spend the majority of their life cycle. This stage is characterized by the cell undergoing normal growth processes and preparing for division. Interphase consists of three sub-phases: G1, S, and G2. The G1 Phase is focused on cell growth and accumulation of resources; the S Phase involves the duplication of chromosomes; and the G2 Phase is when the cell completes preparations for mitosis.
A fact from studies on the cell cycle indicates that most cells are in the interphase at any given time, with only about 7% being in the mitotic phase of the cell cycle. Consequently, if 100 cells were observed under a microscope, approximately 93 of them would be in various stages of interphase, not actively dividing.
