Final answer:
Cell division in eukaryotic cells includes the division of the nucleus, known as mitosis, and the division of the cytoplasm, known as cytokinesis. These two steps result in the formation of two new daughter cells.
Step-by-step explanation:
Cell division, which includes division of the nucleus and cytoplasm, is a process by which a parent cell divides into two new daughter cells. This cell division consists of two main steps: mitosis and cytokinesis. Mitosis is the division of the nucleus, and it occurs in four phases: prophase, metaphase, anaphase, and telophase. Cytokinesis is the division of the cytoplasm, which is the final stage of cell division resulting in the formation of two separate daughter cells.
While the actual figure labeled with the letters A, B, C, and D is not provided in the question, based on the given descriptions of cell division and its stages, the division of the nucleus and the cytoplasm, as a whole process, is represented by the phases of mitosis followed by cytokinesis.
