Question
diagram shows the major stages of the cell cycle and the percentage of time spent in h phase. Which statement best describes why a cell spends the majority of Its time in interphase? A The cell is growing and carrying out processes such as metabolism and DNA replication. B The cell is aging and processes are stopping as lysosomes clear dead cell matter away. C The cell needs time to synthesize spindle fibers to complete mitosis. D The cell needs time to complete cytokinesis

To answer this question, we need to understand what happens during the cell cycle, particularly during interphase.Step 1: Understand the cell cycleThe cell cycle consists of two major phases: interphase and the mitotic (M) phase. Interphase is the period where the cell spends most of its time and is involved in growth and DNA replication. The M phase includes mitosis and cytokinesis, where the cell divides into two daughter cells.Step 2: Analyze the optionsA. During interphase, the cell grows, carries out normal metabolic processes, and duplicates its DNA in preparation for cell division. This is the longest phase of the cell cycle.B. Aging and the clearing away of dead cell matter by lysosomes is not the primary function of interphase.C. While the synthesis of spindle fibers is important for mitosis, it is not the reason why the cell spends the majority of its time in interphase.D. Cytokinesis is the process of cytoplasmic division and occurs after mitosis, but it is not the reason for the extended duration of interphase.Step 3: Choose the best statementBased on our understanding, the best statement that describes why a cell spends the majority of its time in interphase is:A. The cell is growing and carrying out processes such as metabolism and DNA replication.Answer: A
