Answer:
Arrow 1 represents interphase and arrow 2 represents mitosis
Step-by-step explanation:
The cell cycle is generally divided into two phases:
- the interphase, and
- the M or mitotic phase
The interphase represents the period between the telophase of one cell division and the metaphase of another. This is the period the cell uses to prepare itself for active division. It takes up a large chunk of the cell cycle and it is further divided into:
- the G1 phase which represents the period of cell growth and increase in volume,
- the S phase which represents the period during which DNA is synthesized, and
- the G2 phase which represents the period during which protein is synthesized.
The mitotic phase represents the period of active division. It is further divided into the prophase, the metaphase, the anaphase, and the telophase.
Hence, the first arrow (1) of the model represents the interphase while the second arrow (2) represents the mitotic phase.
