it is called a sex pilus
Conjugation in bacteria occurs through a structure known as a pilus, which is a filamentous appendage on the cell surface. The pilus facilitates the transfer of genetic material, such as plasmids, between bacterial cells during conjugation.
Bacteria with the F plasmid (free or integrated) make pili (singular pilus, sometimes referred to as the sex pilus) to connect with bacteria that do not have the F plasmid to initiate DNA transfer. However, the pili are actually used as a harpoon to reel in the other bacteria so that physical contact between the membranes of the bacteria could be made. DNA is only transferred after the fusion of the cell membranes. It is also a common misconception to think that bacterial conjugation is like 'sex' since it does not involve recombination of genes or cycles of haploidy and diploidy.
In bacteria, genes may be transferred through a pilus in a process called conjugation. Conjugation allows for the transfer of genetic material, such as plasmids, between bacterial cells. This transfer of genes can contribute to genetic diversity and the acquisition of new traits in bacterial populations.
== == transformation ------------------------------------------------------------------------------------------------------- Transformation is the process in which a bacteria takes in DNA from the environment. Reference: http://en.wikipedia.org/wiki/Transformation_(genetics) By the way, transduction is the process of DNA transfer by the action of a virus (bacteriophages). The other method of DNA exchange between bacteria is called conjugation, which is the transfer of DNA between bacteria by physical contact.

No, flagella are used for movement, not for conjugation in bacteria. Conjugation involves the transfer of genetic material between bacteria through a pilus, a specialized appendage.

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or a bridge-like link between two cells. In bacteria, it is a parasexual way of reproduction. It's a horizontal gene transfer process, like transformation and transduction, but it doesn't entail cell-to-cell communication.
The sex pilus is a filamentous structure on the surface of bacterial cells that is involved in the process of conjugation, which is a means of horizontal gene transfer between bacterial cells. It serves as a bridge through which the transfer of genetic material, such as plasmids, can occur between donor and recipient bacterial cells.
Bacteriophage is a type of virus that infects bacteria. It uses its protein capsid to inject its genetic material into a bacterial cell and replicate. Pilus is a structure found on bacteria that can be used for conjugation, the transfer of genetic material between bacterial cells.

Bacterial structures involved in DNA passage include pili, which can facilitate DNA transfer between bacteria through conjugation, and plasmids which are small, circular DNA molecules that can be passed between bacteria. Additionally, some bacteria can take up DNA from their environment through a process known as transformation.
conjugation occurs between two bacterial cells and transfers DNA in the form of plasmids. this is one way to transfer of genetic material - it is not sexual reproduction, The other two ways to transfer genetic material between bacteria are transformation and transduction. In order to be able to perform coagulation (transfer of a plasmid) the bacteria must have an F factor (DNA that codes for the PILI protein, which allows the bacteria to create a bridge through which the bacteria inject the plasmid to another bacteria). Bacteria with F factor is called F+, and without it is called F-. F+ can transfer the plasmid to an F- bacteria.
Transduction
Bacterial cidal kills the bacteria, while bacterial static only stops it from growing and reproducing.
Bacterial structures involved in the passage of DNA into or out of the cell include pili, which facilitate the transfer of DNA between bacterial cells through conjugation, and the cell membrane, which allows for DNA uptake during transformation or release during secretion. Additionally, some bacteria use specialized structures such as plasmids or phages to transfer genetic material between cells.
