Q6.8. Which of the following statements is FALSE? The nuclear envelope dissolves in metaphase and reforms in telophase. In prophase, chromosomes condense into compact structures. The spindle forms and attaches to chromosomes in prometaphase. In anaphase, each sister chromatid moves toward the spindle pole to which it is attached.

If plant cells had the following % of their cells in these stages of mitotic cell division and % of cells reflects how much time they spend in each stage: Interphase=74.9% Prophase=17.3% Metaphase=3.3% Anaphase=D1.8% Telophase=D2.7% and Animals had the following %s: Interphase3D62.5% Prophase-D31.5% Metaphase=3.3% Anaphase=D2.0% Telophase%3D0.7%. Which of the following can we NOT conclude? O A. Both plants and animal cells spend most of their time in interphase, doubling all of the organelles and DNA requires a lot of time. OB.Animal cells spend more of their time in mitosis (dividing the nucleus) than plant cells do. O C. Plant cells spend more time in interphase and telophase than animal cells and animal cells spend more time in prophase, and anaphase than plant cells. OD. Plant cells divide more quickly than animal cells.
