Label D – Mitosis: during mitosis the cell divides its nucleus and cytoplasm to produce two daughter cells.

Label E- Interphase :  A stage of cell growth and metabolic activity. The G1,S and G2 phases together called interphase.  

Label A  - G1 phase

Label B - S phase

Label C - G2 phase

Label D - Mitosis
