A researcher examining a root tip observes a plant cell with condensed sister chromatids, kinetochores with attached microtubules, and individual chromosomes that are aligned at the equatorial plate of the cell. Which of the following best describes what the next process will be in the cell?
A. Homologous chromosomes (each with two sister chromatids) will move toward opposite poles of the cell.
B. Paired chromatids will separate, and the new daughter chromosomes will move toward opposite poles of the cell.
C. The nuclear envelope will break down, and the spindle will begin to form.
D. The chromatin will decondense, and the daughter cell will enter interphase.
