How do state governments in the United States reflect the federal government?

Also Examples of similarties in each of the three branches of government.

Thank you!

The Constitution requires each state to have a republican form of government. There is no requirement for 3 branches, although all states have three explicit branches; there is no requirement for a two-chambered legislature, although all states except Nebraska have a two chambered legislature.

States, of course, are affected by the Supremacy clause and thus all other laws passed by the national government. But in terms of Constitutional requirements, that's it.

State governments must conform to the constitution and policies of the federal government.

The three branches of government have autonomy in the administration of their departments.
