In plant cells, how does cytokinesis take place?

• A. Through the contraction of muscle fibers
• B. By forming a cleavage furrow
• C. With the formation of a cell plate
• D. Through the fusion of debris

Answer: (C)

In plant cells, cytokinesis occurs through the formation of a cell plate, which is a process that distinguishes it from animal cells. During cell division, vesicles filled with cell wall materials collect at the middle of the dividing cell, coalescing to form the cell plate. This structure gradually expands outward, eventually fusing with the existing cell membrane and developing into a new cell wall that separates the two daughter cells. This method is vital for plant cells because they have a rigid cell wall that cannot simply pinch inwards like animal cells, which utilize a cleavage furrow. The creation of a cell plate allows plant cells to maintain their structural integrity while also ensuring that the newly formed cells properly separate, allowing them to continue growing and functioning.
