• D. Photosynthesis

Answer: (D)

Verified step by step guidance

1. Understand the cell cycle: The cell cycle is a series of phases that cells go through to divide and produce new cells. It includes Interphase, Mitosis, and Cytokinesis.
2. Define Interphase: Interphase is the phase where the cell prepares for division by growing and replicating its DNA. It consists of three sub-phases: G1, S, and G2.
3. Define Mitosis: Mitosis is the phase where the cell's nucleus divides, resulting in two identical nuclei. It includes stages such as prophase, metaphase, anaphase, and telophase.
4. Define Cytokinesis: Cytokinesis is the final phase of the cell cycle where the cytoplasm divides, resulting in two separate cells.
5. Identify the unrelated term: Photosynthesis is a process by which plants, algae, and some bacteria convert light energy into chemical energy. It is not a phase of the cell cycle.
