Answer:
Analogous structures can be defined as those structures which have been evolved in the living organisms that exhibit similar function but different in structure and origin. The bacterial flagella is group of thread like structure that are used for locomotion by the bacterial cell. The structures analogous for the bacterial flagella are flippers in the whales and dolphins, joined legs of insects and vertebrates used for the locomotion, and fins of fishes.
The three animal structure that are analogous to bacterial flagella are:
The caudal tail in fish.
Sperm flagellum.
Flukes of whales.
Analogous organs are organs that has different structures but perform similar functions.
Example: the wings of insect and feathers of bird, both have similar function but different anatomy.
Now, bacterial flagella help it to swim and locomotion, similarly the tail in fish helps the fish to swim in water bodies, sperm flagellum help it to swim in the body fluid, and the tail of the whale called fluke helps in swimming and locomotion.
Hence, all have similar function but different structures.
