Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants
A)the spindles contain microfibrils in addition to microtubules, whereas animal spindles do not contain microfibrils.
B)sister chromatids are identical, but they differ from one another in animals.
C)a cell plate begins to form at telophase, whereas in animals a cleavage furrow is initiated at that stage.
D)chromosomes become attached to the spindle at prophase, whereas in animals chromosomes do not become attached until anaphase.
E)spindle poles contain centrioles, whereas spindle poles in animals do not.

Question

Quizplus · Accepted Answer

The key difference between higher plants and animals during mitosis and cytokinesis is the way in which cytokinesis occurs. In animals, a cleavage furrow is initiated during telophase and gradually deepens until the cell is divided in two. In contrast, in higher plants, a cell plate begins to form at the center of the dividing cell during telophase. This cell plate grows outward towards the cell walls until it fuses with them, resulting in two daughter cells.
