Solution

During cytokinesis:

  1. The cytoplasm is divided between the cells: This is true. Cytokinesis is the process where the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.

  2. Chromosomes are pulled to opposite poles of the cell: This is not true. This process occurs during anaphase, a phase of mitosis, not during cytokinesis.

  3. Contraction of microfilaments pinches off two cells from one: This is true. During cytokinesis, a ring of actin and myosin microfilaments contracts inside the cell membrane, creating a cleavage furrow and eventually pinching the cell into two separate cells.

  4. Spindle fibers attach to chromosome centromeres: This is not true. This process occurs during metaphase, a phase of mitosis, not during cytokinesis.

  5. Cell membrane constricts around the center of the cell: This is true. During cytokinesis, the cell membrane constricts at the center of the cell, eventually dividing the cell into two daughter cells.
