Final answer:
The term for a bacterial cell with a single tuft of flagella at one end is lophotrichous.
Step-by-step explanation:
The term that refers to a bacterial cell having a single tuft of flagella at one end is lophotrichous. For example, Pseudomonas aeruginosa is a gram-negative bacterium with lophotrichous flagella. Monotrichous flagella refer to bacteria with a single flagellum at one end, such as Vibrio cholerae. In contrast, amphitrichous flagella are found at both ends of cells like Spirillum minor, and peritrichous flagella cover the entire surface of bacteria like Escherichia coli.
