How does cytokinesis differ between plant and animal cells?
A
In plant cells, cytokinesis involves the formation of a cleavage furrow, while in animal cells, a cell plate forms.
B
In plant cells, cytokinesis is driven by microtubules, while in animal cells, it is driven by chloroplasts.
C
In plant cells, a cell plate forms, while in animal cells, a cleavage furrow forms.
D
In plant cells, cytokinesis occurs through binary fission, while in animal cells, it occurs through mitosis.
Verified step by step guidance1
Understand that cytokinesis is the process of cytoplasmic division that follows the end of mitosis, resulting in two daughter cells.
Recognize that in animal cells, cytokinesis occurs through the formation of a cleavage furrow. This furrow is created by a contractile ring composed of actin and myosin filaments that pinches the cell membrane inward until the cell is divided into two separate cells.
In contrast, plant cells have a rigid cell wall that prevents the formation of a cleavage furrow. Instead, cytokinesis in plant cells involves the formation of a cell plate.
The cell plate in plant cells forms from vesicles derived from the Golgi apparatus. These vesicles coalesce at the center of the cell, eventually fusing to form a new cell wall that separates the two daughter cells.
Clarify that the statement about microtubules and chloroplasts is incorrect. Microtubules are involved in the formation of the cell plate in plant cells, but chloroplasts do not drive cytokinesis in animal cells. The correct distinction is the formation of a cell plate in plant cells and a cleavage furrow in animal cells.
