Cytokinesis in animal and plant cells: cleavage and cell plate

Cytokinesis in Animals--8.6

• Occurs in a process known as cleavage.
• The cell forms a cleavage furrow
• At the site of the furrow, actin and myosin together contracts
• Cleavage furrow deepens and eventually pinches the parent cell into two, producing two parent cells.

Cytokinesis in Animals--8.6

• First sign of cleavage is the cleavage furrow
• Actin and myosin contracts when interacting at the site of the cleavage
• The cleavage furrow deepens and pinches the cell into two, producing two daughter parent cells
• 

Cytokinesis in Plants--9.6

• Membranous vesicles containing cell wall materials collect at the middle of the parent cell
• The vesicles fuses, forming a cell plate
• The cell plate grows outward and fuses with the plasma membrane
• Joins the parental cell wall, producing two parental cells
•
