Detailed explanation-1: -Instead of plant cells forming a cleavage furrow such as develops between animal daughter cells, a dividing structure known as the cell plate forms in the cytoplasm and grows into a new, doubled cell wall between plant daughter cells. It divides the cell into two daughter cells.

Detailed explanation-2: -Cytokinesis is the division of the cytoplasm that occurs as one of the last steps in cellular division. The biggest and most noticeable difference between plant and animal cytokinesis is that plants form a cell plate while dividing, whereas animal cells form a cleavage furrow.

Detailed explanation-3: -Animal cell cleavage furrow formation is caused by a ring of actin microfilaments called the contractile ring, which forms during early anaphase. Myosin is present in the region of the contractile ring as concentrated microfilaments and actin filaments are predominant in this region.

Detailed explanation-4: -Cleavage furrows are not found in plant cells, because plant cells have rigid walls that cannot be bent. Instead, plant cells grow new cell walls from the inside using a cell plate.

Detailed explanation-5: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
