Question

the diagram shows the major stages of the cell cycle and the percentage of time spent in each 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.

Explanation:

Interphase is a crucial stage. During this time, the cell grows (increases in size), metabolizes (carries out chemical reactions for energy and function), and replicates its DNA (prepares for cell division). Option B is incorrect as interphase is not about aging and stopping processes. Option C - spindle fiber synthesis mainly occurs in prophase (a part of mitosis, not interphase). Option D - cytokinesis is the final step of cell division (after mitosis), not the main activity in interphase. So, the cell spends majority of time in interphase for growth and key processes like metabolism and DNA replication.

Answer:

A. The cell is growing and carrying out processes such as metabolism and DNA replication.
