In plant cells, which mechanism most directly accomplishes cytokinesis?
A
Fragmentation of the plasma membrane followed by membrane resealing to generate two cells
B
Disassembly of the nuclear envelope to allow the cytoplasm to separate into two daughter cells
C
Contraction of an actin-myosin ring that creates a cleavage furrow to pinch the cell in two
D
Formation of a cell plate via Golgi-derived vesicles that fuse at the center and expand outward to form a new cell wall
Verified step by step guidance1
Understand that cytokinesis is the process by which the cytoplasm of a single eukaryotic cell divides to form two daughter cells after mitosis or meiosis.
Recall that in animal cells, cytokinesis typically occurs through the contraction of an actin-myosin ring that creates a cleavage furrow, pinching the cell into two separate cells.
Recognize that plant cells have a rigid cell wall, which prevents the formation of a cleavage furrow, so they use a different mechanism for cytokinesis.
Identify that in plant cells, cytokinesis is accomplished by the formation of a cell plate, which begins as vesicles derived from the Golgi apparatus that move to the center of the cell.
These Golgi-derived vesicles fuse at the center of the dividing cell, gradually expanding outward until a new cell wall is formed, effectively separating the two daughter cells.
