Can anyone explain electrochemical cells in solution

Can anyone explain electrochemical cells in solution? salt bridge?

I understand parts of this topic but i need a bit more understanding with the anode and cathode?
Which compound(Zn+, Cu+) will be on which electrode and where would the electrons flow.

I used these videos to help me understand electrochemical cells:
