Drag the descriptions or images to the correct box to show your understanding of the external structures of bacterial cells.

flagella: has runs and tumbles

pili: involved in bacterial conjugation

Explanation:

Flagella can be described as hair-like, long and thin appendages which are used by the bacteria for movement. Some bacteria have only a single flagellum while the others might have many of these. The flagella also help the bacteria to track down food particles.

Pili can be described as external structures of the bacteria that allow the bacteria to attach to different substrates. Pili also help in the transfer of genetic material from one bacteria to the other bacteria.
