Question

Compare and contrast cytokinesis in animal and plant cells.

Answer 1

Answer:

Sample Response: Cytokinesis occurs in both animal and plant cells. It is the division of the cytoplasm, which is the final stage of the cell cycle. In animal cells, the cell membrane pinches together around the middle of the cell to divide the cytoplasm. In plant cells, the process is a little different. Because the cell wall of a plant cell is rigid, it does not pinch in like the more flexible cell membrane in animal cells. Instead, a structure called a cell plate forms across the middle of the cell. The cell plate moves outward and eventually fuses with the cell membrane to divide the cell into two cells. Then, new cell walls form around the cell membranes.

Answer 2

Answer:  Animal cells divide by a cleavage furrow. Plant cells divide by a cell plate that eventually becomes the cell wall. Cytoplasm and cell membranes are necessary for cytokinesis in both plants and animals.
