Answer:
Cell plate.
Explanation:
The FtsZ gene encodes the protein called FtsZ. This protein plays an important role in the bacterial cell division. The FtsZ protein is Filamenting temperature-sensitive mutant Z.
This protein helps in the formation of cell walls of daughter cells as it directs the formation of cell plate during cell division. This protein allows the cytoskeletal scaffold of the Z ring.
Thus, the correct answer is option (2).
