Question

station 7: telophase

1. what occurs after telophase to complete the process of cell division?
2. which of the following does not occur during telophase? cross out the untrue statements below:

a. chromosomes spread out into chromatin.
b. nuclear envelope reforms around chromosomes.
c. nucleolus disappears.
d. spindle fibers break down.
e. centrioles dissolve and disappear.

Explanation:

For question 31: Telophase is the final stage of nuclear division; the physical splitting of the cell cytoplasm (cytokinesis) follows to finish cell division.
For question 32:

• a: Chromosomes decondense into chromatin during telophase, so this is true.
• b: The nuclear envelope reforms around the separated chromosomes in telophase, so this is true.
• c: The nucleolus disappears during prophase, not telophase (it reforms in telophase), so this is false.
• d: Spindle fibers break down as telophase progresses, so this is true.
• e: Centrioles do not dissolve and disappear during telophase; they remain for future cell divisions, so this is false.

Answer:

1. Cytokinesis (the division of the cell's cytoplasm) occurs after telophase to complete cell division.
2. The statements that do NOT occur during telophase are:

c. Nucleolus disappears.
e. Centrioles dissolve and disappear.
