Verified step by step guidance1
Understand the process of cytokinesis, which is the division of the cytoplasm to form two separate daughter cells after mitosis.
Recognize that in animal cells, cytokinesis occurs through the formation of a cleavage furrow. This is a contractile ring composed of actin and myosin filaments that pinches the cell membrane inward, eventually splitting the cell into two.
In contrast, plant cells have a rigid cell wall that prevents the formation of a cleavage furrow. Instead, plant cells undergo cytokinesis by forming a cell plate.
The cell plate in plant cells is formed by the fusion of vesicles derived from the Golgi apparatus at the center of the cell. These vesicles coalesce to form a new cell wall that separates the two daughter cells.
Conclude that the key difference is that plant cells form a cell plate during cytokinesis, while animal cells form a cleavage furrow.
