Verified step by step guidance
1
Understand the stages of the cell cycle: The cell cycle consists of interphase (G1, S, G2 phases) and the mitotic phase (mitosis and cytokinesis). Mitosis is further divided into prophase, metaphase, anaphase, and telophase.
Recognize the role of cytokinesis: Cytokinesis is the process that follows mitosis, where the cytoplasm of a parent cell is divided into two daughter cells. It is distinct from the stages of mitosis itself.
Identify the formation of the cleavage furrow: The cleavage furrow is a structure that forms during cytokinesis. It is the indentation that begins to form in the cell membrane, leading to the division of the cell into two separate cells.
Differentiate between mitosis and cytokinesis: While mitosis involves the division of the nucleus, cytokinesis involves the division of the cytoplasm. The cleavage furrow is specifically associated with cytokinesis, not the earlier stages of mitosis.
Conclude that the cleavage furrow forms during cytokinesis: Based on the understanding of the cell cycle and the role of cytokinesis, the cleavage furrow forms during cytokinesis, which is the final step in the cell division process.
