11. Cell Division

"Cytokinesis" refers to __________.

Following cytokinesis in an animal cell, how many centrioles does each new daughter cell possess?

In animal cell mitosis, the cleavage furrow forms during which stage of the cell cycle?

You would know that a dividing cell was a plant cell rather than an animal cell if you saw that __________.

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

When a fruit fly embryo first begins to develop, a large cell is generated that contains over 8000 genetically identical nuclei. What is most likely responsible for this result?

DRAW IT Draw one eukaryotic chromosome as it would appear during interphase, during each of the stages of mitosis, and during cytokinesis. Also draw and label the nuclear envelope and any microtubules attached to the chromosome(s).

An organism called a plasmodial slime mold is one large cytoplasmic mass with many nuclei. Explain how such a 'megacell' could form.

Compare cytokinesis in plant and animal cells. In what ways are the two processes similar? In what ways are they different?
