Answer:
Without seeing the plant cell, it is not possible to determine the exact stage of mitosis the plant cell is in. However, during metaphase, the chromosomes align at the equator of the cell and are attached to the spindle fibers. During anaphase, the spindle fibers separate the sister chromatids and pull them towards opposite poles of the cell. During telophase, the chromosomes reach the poles of the cell, and a new nuclear envelope begins to form around each set of chromosomes. Therefore, if the plant cell has chromosomes that are aligned in the middle of the cell, it is likely in metaphase. If the chromosomes are being pulled towards opposite poles of the cell, it is likely in anaphase. If the chromosomes have reached the poles and new nuclear envelopes are forming, it is likely in telophase.
