Question

In most respects, cell division is similar between plant and animal cells. Which of the following events occurs by a different mechanism in animal and plant cells?

A.) condensation of chromosomes at the beginning of cell division
B.) separation of the cell into two daughter cells
C.) chromosomes being pulled apart by the microtubules of the mitotic spindle
D.) alignment of chromosomes in the center of the cell

Answer 1

The event that occurs by a different mechanism in animal and plant cells during cell division is the separation of the cell into two daughter cells. In animal cells, daughter cells are separated by an actin ring, whereas in plant cells, daughter cells are separated by a cell plate.

Step-by-step explanation:

In most respects, cell division is similar between plant and animal cells. In animal cells, daughter cells are separated by an actin ring, which constricts to form a cleavage furrow. This cleavage furrow gradually deepens until the parent cell is divided into two daughter cells. In plant cells, on the other hand, daughter cells are separated by a cell plate. During cytokinesis, the Golgi vesicles fuse at the metaphase plate and form a cell plate.

This cell plate then grows outward towards the cell walls, ultimately leading to the formation of new cell walls that separate the two daughter cells. Animal cells undergo cytokinesis by forming a cleavage furrow, which is the constriction of the actin ring that leads to cytoplasmic division. On the other hand, plant cells perform cytokinesis by forming a cell plate during cell division.
