Yes.
Yes they do have a brain everything that is living has a
brain.

Actually that's not completely true... Trees for instance do not
have brains, yet they are living. I think the question is relevant
to an actual brain in the anatomy, not a metaphorical brain of a
living thing. Another living thing that does not have a brain is
fungi, it's still living, yet has no brain. An amoeba? Also does
not have brain. Cells do not have brains. I think I've proven my
point. Thank you.
