Question

How does cytokinesis differ in plant and animal cells?

A. In animals the process leads to only three cells. In plants, the process produces four cells.
B. In plants the cells are physically separated, while animal cells are still joined.
C. In plants the result is four cells; in animals the result is two cells.

D. In animals the cell's area physically separated, while plants are divided by a cell plate.

Answer 1

Cytokinesis differs in plants and animals, wherein animal cells form an actin ring leading to a cleavage furrow and separation, while plant cells form a cell plate that results in two new cells with distinct cell walls.

Step-by-step explanation:

Cytokinesis differs in plant and animal cells in terms of the mechanisms involved in physically separating the newly formed daughter cells. In animal cells, cytokinesis occurs through the formation of an actin ring that constricts the cell's cytoplasm, resulting in a cleavage furrow that pinches the cell into two separate daughter cells. In plant cells, however, a structure called a cell plate forms at the site of division, which grows outwards to meet the cell walls, eventually leading to the formation of new plasma membranes and cell walls for each of the two daughter cells.

Answer 2

D.

Step-by-step explanation:

Animal cells have a cleavage furrow which will pinch the cytoplasm into two nearly equal parts. While plant cells have a cell plate that forms halfway between the divided nuclei.
