Multiple Choice

FtsZ is a bacterial cytoskeletal protein that forms a contractile ring involved in binary fission. Its function is analogous to ________.

the cleavage furrow of eukaryotic animal cells.

the cell plate of eukaryotic plant cells.

Verified step by step guidance

Understand the role of FtsZ in bacterial cells: FtsZ is a protein that forms a ring at the future site of the septum in bacterial cell division, similar to how certain structures function in eukaryotic cells during cell division.

Identify the analogous structure in eukaryotic cells: In eukaryotic animal cells, the cleavage furrow is the structure that forms during cytokinesis, helping to divide the cell into two daughter cells.

Compare the function of FtsZ with the cleavage furrow: Both FtsZ and the cleavage furrow are involved in the process of physically dividing the cell into two separate entities.

Consider the other options: The cell plate in plant cells, the mitotic spindle, and the microtubule-organizing center have different roles in cell division and organization, which are not directly analogous to the contractile function of FtsZ.

Conclude that the function of FtsZ is most similar to the cleavage furrow in eukaryotic animal cells, as both are involved in the constriction and division of the cell during the final stages of cell division.
