Mitosis and Meiosis

Briefly describe the difference between telophase I and II.

• Telophase I results in two diploid cells, while telophase II results in four haploid cells.

• Telophase I involves the separation of homologous chromosomes, while telophase II involves the separation of sister chromatids.

• Telophase I occurs only in animal cells, while telophase II occurs only in plant cells.

• Telophase I is part of mitosis, while telophase II is part of meiosis.

What would happen to cell division if a chemical was put in the cell that did not allow for cell division to occur?

• The cell would continue to divide normally.

• The cell would skip the affected phase and continue with the next phase.

• The cell cycle would be arrested at the stage where the chemical acts.

• The cell would immediately die.
