11. Cell Division

In animal cell cytokinesis, a cleavage furrow is ________.

Which of the following are primarily responsible for cytokinesis in plant cells?

FtsZ is a bacterial cytoskeletal protein that forms a contractile ring involved in binary fission. Its function is analogous to ________.

Through a microscope, you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. This cell is most likely a. an animal cell in the process of cytokinesis. b. a plant cell in the process of cytokinesis. c. a bacterial cell dividing. d. a plant cell in metaphase.

Which statement about the daughter cells following mitosis and cytokinesis is correct? a. They are genetically different from each other and from the parent cell. b. They are genetically identical to each other and to the parent cell. c. They are genetically identical to each other but different from the parent cell. d. Only one of the two daughter cells is genetically identical to the parent cell.

Identify at least two events in the cell cycle that must be completed successfully for daughter cells to share an identical complement of chromosomes.

The drug cytochalasin B blocks the function of actin. Which of the following aspects of the animal cell cycle would be most disrupted by cytochalasin B? a. spindle formation b. spindle attachment to kinetochores c. cell elongation during anaphase d. cleavage furrow formation and cytokinesis
