Question

how do prokaryotic cells move? by growing larger by dividing into two by using their nucleus by using their flagellum

Explanation:

Prokaryotic cells, like bacteria, use flagella (long, whip - like structures) for movement. Growing larger is related to cell growth, dividing into two is a form of reproduction (binary fission), and prokaryotic cells do not have a true nucleus (they have a nucleoid region).

Answer:

By using their flagellum
