Homework Answers
A) in animal cells the cytokinesis occurs via cleavage furrow, and the plant cells cytokinesis occurs via cell plate.
a) animal cell, b) plant cell.
B) in both images the cytokinesis is shown.
C) c) is the contractile ring which forms during the cell division of animal cells, d) is the cell plate which forms during the cell division of the plant cells.
D) actin and myosin forms the contractile ring, this brings the membranes close to each other so as to divide the cell to two.
