Amphitrichous means having one flagellum (or a tuft) at each end of the cell. Lophotrichous means having a tuft of flagella at one or both ends.

Absolutely not. It is only relevant for specialists in microbiology or students taking advanced courses in that field.

Think of 'amphi-' (meaning 'both' or 'on both sides', like in 'amphitheater') + 'tricha' (relating to hair, like flagella). So, 'hairs on both sides'.

Conceptual Metaphor

A bacterium as a tiny submarine with a propeller at both the bow and the stern, enabling versatile movement.
