Bacterial cells
They do not have a well-defined nucleus (unlike plant and animal cells)
They have cell walls (unlike an animal cell)
They have ribosomes
I have attached an image of a bacterial cell. you can see all the structures mentioned above.
I hope this helps! I'm happy to answer any other questions you might have :)
