Verified step by step guidance

Begin by understanding the different types of flagellar arrangements on bacterial cells. Flagella are appendages that help in bacterial motility, and their arrangement can vary.

Peritrichous flagellation refers to flagella distributed all over the surface of the bacterial cell. Lophotrichous flagellation involves a cluster of flagella at one or both ends of the cell.

Monotrichous flagellation means a single flagellum at one end of the bacterial cell. Amphitrichous flagellation involves flagella at both ends of the cell. Atrichous means no flagella are present.

Examine the image provided. Observe the bacterial cell and note the presence and arrangement of flagella. In the image, there is a cluster of flagella at one end of the cell.

Based on the observation, identify the type of flagellar arrangement. The presence of a cluster of flagella at one end suggests a lophotrichous arrangement.
