Bacteria and Fungi come under different categories; the former one is the prokaryotic cell while the latter one is Eukaryotic cells. Apart from this, there are many differences between them like bacteria need a host to live, and they can be autotrophs as well as heterotrophs, whereas fungi grow their own and are heterotrophs which depend on others for their food. Bacteria do not have nuclear membrane enclosing nucleus, while Fungi (eukaryotes) have well- defined nucleus surrounded by the nuclear membrane.
