Verified step by step guidance

Understand the concept of bacterial conjugation: Conjugation is a process where genetic material is transferred between bacterial cells through direct contact.

Identify the cellular structure responsible for conjugation: Pili are the structures that facilitate the transfer of DNA during conjugation.

Differentiate between the listed structures: Cilia and flagella are primarily involved in movement, while fimbriae are used for attachment to surfaces.

Recognize the role of pili: Pili, specifically the sex pilus, form a bridge between two bacterial cells, allowing the transfer of plasmids.

Conclude that pili are the correct answer: Based on their function in conjugation, pili are the cellular structures involved in this process.
