Verified step by step guidance1
Understand the process of cytokinesis, which is the final step in cell division where the cytoplasm divides to form two separate daughter cells.
Recognize that cytokinesis differs between plant and animal cells due to structural differences. Plant cells have a rigid cell wall, while animal cells do not.
In animal cells, cytokinesis occurs through the formation of a cleavage furrow. This is a contractile ring composed of actin and myosin that pinches the cell membrane inward until the cell is divided into two separate cells.
In plant cells, cytokinesis occurs through the formation of a cell plate. Vesicles from the Golgi apparatus coalesce at the center of the cell, forming a new cell wall that separates the two daughter cells.
Compare the two processes: animal cells use a cleavage furrow due to their flexible cell membrane, while plant cells form a cell plate to accommodate their rigid cell wall.
