WebThe cell cycle consists of interphase and the mitotic (M) phase. In the M phase, the cell undergoes mitosis or nuclear and cytoplasmic division. Mitosis consists of multiple stages: interphase, prophase,metaphase, anaphase, and telophase. During interphase, DNA is replicated. In prophase, the chromatin forms distinct chromosomes.

Cell A has a large, dark nucleolus surrounded by greyish material (chromatin) that is enclosed within the nuclear membrane. A cell wall makes a box around each cell and the plasma membrane would be located just inside this box, though we cannot easily see it. WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
